keepalived: Update to version 2.3.4

- Update from version 2.3.1 to 2.3.4
- No change to rootfile
- Changelog
    2.3.4
	Improvements
	    core: properly restore process priorities after a reload.
	    core: allow specifying iproute_usr_dir even if no iproute2 support.
	    core: include network namespace name when error opening namespace fds.
	    core: resolve lang warning when comparing ordering of function addresses.
		The only reason function addresses are compared is with a red-black
		tree to quickly convert a function address into its name. It clearlt
		isn’t a sandard thing to do to compare ordering of function addresses,
		but it this case it is quite valid.
	    core: stop repeatedly calling getpid(). We only need to call getpid() once
		per process, and can then save the value. A PID of a given process is
		never going to change!
	    core: add code to calculate maximum stack usage and use it for no_swap.
		When a process has no_Swap specified, if we want to ensure that the
		stack is resident in memory we need to know the maximum size that it
		is likely to grow to. This commit adds diagnostic code (usually
		disabled) to report maximum usage, so that the code can be updated to
		know, in advance, the maximum likely stack usage.
	    core: set CLOEXEC flag on all file descriptors except stdin/stdout/stderr.
	    core: set CLOEXEC flag on streams (fopen/popen).
	    snmp: set CLOEXEC on file descriptors opened by snmp.
	    snmp: use close_range() if available for closing snmp file descriptors.
	    core: call close_range() if available before exec’ing scripts.
	Fixes
	    build: fix snap build process.
	    vrrp: fix segfault at reload when DBus re-enabled. If dbus as enabled,
		then a reload disabled it, and another reload re-enabled it, then
		keepalived would often segfault. This is resolved by clearing
		dbus_startup_completed when dbus is stopped.
	    vrrp: fix track_process warn identified by -Wflex-array-member-not-at-end.
	    notify: fix resolving group name to gid for scripts. If a group had a
		large number of members, the memory allocated for getgrnam_r() could
		be insufficient and the call fail. This commit now allocates as much
		memory as the size of the group file, which should be sufficient.
	    ipvs: resolve infinity loop when SMTP_CHECKers have ‘host’ config.
	    core: fix keepalived not coredumping after a reload. This made it very
		difficult to resolve segfaults occurring due to a reload.
	    vrrp: document and fix specifying iproute_etc_dir and iproute_usr_dir.
	    build: fix some RHEL 7 and friends compilation problems.
	    core: fix memory leak in track_file.
    2.3.3
	New
	    vrrp: don’t allow unicast instance without interface to have a VMAC. If
		the interface is not configured, we can’t know what interface to add
		the VMAC to.
	    vrrp: Add setting IP_FREEBIND/IPV6_FREEBIND socket option. This allows
		creating and configuring unicast sockets before the configured source
		address is added to the system.
	    core: add O_CLOEXEC flag to pidfiles.
	    vrrp: Support logging rate-limiting specified by RFC 9568
	    vrrp: add option for address owner to drop received VRRP packets.
		RFC 9568 (and RFC 5798 and RFC 3768) state that an address owner must
		drop any received VRRP packets. The consequence of this is that if
		there is more than one VRRP instance configured with priority 255 then
		they will all be in master state simultaneously. It seems more
		sensible for such received packets to be processed normally, and all
		but the VRRP instance with the primary IP address will revert to
		backup state. RFC 9568 appears to allow more than one instance to have
		priority 255, since section 8.3.2 was changed from “No more than one
		router on the link is to be configured with priority 255, especially
		if preemption is set” (note the contradiction here) to “only a single
		VRRP Router on the link SHOULD be configured with priority 255” and
		then descibes the situation if there is more than one such router.
		keepalived defaults to processing received packets when the local
		priority is 255, but the option added by this patch allows working in
		accordance with the RFC, i.e. to drop any received packets.
	Improvements
	    core: Allow building on very old systems with kernels < 3.15. Open file
		descriptor locks were introduced in Linux 3.15, so we cannot use that
		type of locking on systems with older kernels (e.g. CentOS 7, which of
		course is no longer supported). Since this problem only occurs on
		kernels no longer supported by keepalived this commit simply removes
		the file locking, rather than implementing a more comprehensive
		solution. It is expected that at some point, in order to simplify the
		code, support for kernels no longer supported by any of the main
		distros will be removed from keepalived.
	    doc: add oldest distro versions with their EOL dates and kernel versions.
	    docker: Install linux-headers pkg to build in Docker.
	    vrrp: handle checking ip utility version properly with BusyBox.
	    snap: Misc snap improvements.
	    build: make default _FORTIFY_SOURCE setting 3. Various distros already
		use _FORTIFY_SOURCE=3 by default, so we should do so too.
	    vrrp: check the iproute2 directories exist when read first file
	    vrrp: create /etc/iproute2 directory if it doesn’t exist.
	    vrrp: Restore priority 255 if duplicate address owner detected. The VRRP
		RFCs assume that only one device is configured as the address owned
		for any VRID. keepalived has extended functionality which detects if
		two (or more) systems are configured as the address owner (this is
		completely invalid configuration). To avoid multiple systems acting as
		address owner, and hence all of them remaining in master mode,
		keepalived will reduce an address owner’s priority to 254 if the other
		device configured as address owner does not go away. This commit
		restores the priority of a vrrp instance to 255 if it had reduced it
		to 254 to avoid multiple VRRP instances simultaneously advertising
		that they are the address owner.
	    vrrp: Only reduce address owner priority if primary ip address lower. If a
		VRRP instance is configured as address owner and it detects another
		device also advertising it is the address owner, only initially reduce
		our priority if our primary IP address is lower than the other
		device’s primary IP address.
	    vrrp: if duplicate address owners, reduce priority if other won’t. If a
		VRRP instance is configured as address owner and it detects another
		device also advertising it is the address owner, we don’t reduce our
		priority if our primary IP address is higher than the other device’s
		primary IP address. However, if the other system, with a lower
		primary IP address, won’t reduce its priority (e.g. it is not a
		keepalived implementation), then we will reduce our priority after a
		suitable time.
	    vrrp: add more helpful log messages if duplicate address owner.
	    vrrp: log rate-limited message if advert has no VIPs.
	    vrrp: log rate-limited warning if VRRPv3 advert interval mismatch.
	    vrrp: it is not an error if VIPs in advert do not match configured. We
		should accept a VRRP advert if the VIPs in an advert do not match our
		configuration, but just log a rate-limited warning.
	    vrrp: update saved master address when receive high priority advert. If we
		are in master state and receive a higher priority advert, saving the
		new master address saves checking VIPs twice.
	    vrrp: include source address in log after receiving a bad advert.
	    vrrp: check that VIPs are not duplicated.
	    vrrp: check TTL/HL and unicast source ip even when not checking VIPs. The
		checking of TTL/HL and unicast source ip was only being done if the
		VIPs were being checked, whereas they should be checked even if the
		VIPs are not being checked.
	    vrrp: change rx_ttl_hop_limit to rx_ttl_hl. The name was confusing since
		it suggested the value was a limit.
	    vrrp: identify unicast peer in unicast_peer block configuration errors.
	    vrrp: detect and reject duplicate unicast_peers in configuration.
	    vrrp: add logging a change of master when detailed logging enabled.
	    vrrp: handle a reload with no more startup_delay. During the
		vrrp_startup_delay time, if keepalived is reloaded with no more
		startup_delay, the startup_delay is never timed out and all received
		adverts is discarded. The commit causes the startup_delay timer to be
		reinstated after a reload with no more startup_delay if the timer has
		not yet expired.
	    vrrp: Skip running not idle vrrp scripts. When a vrrp script is to be run
		(initially or after specified interval), first it is checked if it’s
		in IDLE state. If not a log message is printed informing about
		skipping run due to script being either running or timed out. However
		despite not being idle the code continues to run new script process.
		In heavily loaded systems this caused running multiple instances of
		vrrp script at the same time. This patch brings back missing return,
		which was lost during refactoring.
	    codeQL: update codeQL.yml
	    vrrp: add checks that interface fault flags not inconsistent. When a fault
		is added in down_instance() or cleared in try_up_instance() check that
		the flag that is being modified is not already set or cleared, as
		appropriate. This check is enabled by configure option
		–enable-fault-flags-check.
	    vrrp: use a fault flag if num_track_faults is non zero. It simplifies the
		code to set a fault flag is num_track_faults is non-zero and clear the
		flag if num_track_faults is zero.
	    vrrp: don’t attempt to send advert if socket is closed. This avoids an
		unnecessary log message.
	    vrrp: don’t have multiple tracking objects for a VRRP instance. The code
		did have separate tracking objects for dynamic and non dynamic
		tracking objects for a VRRP instance. It also would add an addition
		dynamic tracking object every time a tracked interface was created,
		causing down_instance() to be called multiple times when an interface
		was deleted and previous creations of the interface. Prior to the
		patch to add fault flag bits this resulted in the vrrp instance not
		coming back up after the interface was recreated. Ths issue of vrrp
		instances remaining in fault state after after deletion and
		re-creation of interfaces is now resolved.
	    vrrp: delay deleting VMACs are parent interface is deleted. The interface
		structure needs to have the ifindex set for the first pass through the
		VRRP instances, but it must be unset when the VMACs are cleaned up.
	    vrrp: don’t change link local IPv6 address when extra added to base if. If
		an additional link local address was added to the base interface of a
		VMAC, keepalived was changing the source address of adverts to be the
		new address. The commit makes keepalived change the source address if
		the one it is using is deleted.
	    track: don’t overwrite track file at startup unless configured to.
	    vrrp: allow interface up debounce timer to exceed 2 * advert interval.
		There was no need to limit the up debounce timer in the same way that
		the down debounce timer has to be limited, so this commit removes the
		2 * advert interval upper limit.
	    vrrp: update delayed start time on reload if vrrp_startup_delay changed.
	    vrrp: ignore IPv6 tentative addresses. We can’t do anything with them, and
		they are not usable, so we now wait until we are notified that the
		address is no longer tentative before we consider using it.
	Fixes
	    parser: Fix error handling for HEX_STR parsing in UDP_CHECK. Fixes an
		issue where HEX_STR values with a trailing 0xff were incorrectly
		treated as errors. This HEX_STR is used in UDP_CHECK configuration,
		particularly in the payload and require_reply fields.
	    ipvs: Fix segfault when using track_file checker.
	    ipvs: Fix delay_loop for TCP_CHECK.
	    scheduler: Fix segfault caused double erase from child_pid rbtree. In a
		situation when a child was timed out, but not yet processed, the
		thread is THREAD_CHILD_TIMEOUT type and remains on ready queue. If it
		gets terminated in this state, it needs to be removed from rb tree
		child_pid and transitioned to THREAD_CHILD_TERMINATED, but without
		additional moving it to ready queue as it is already there. The erase
		from child_pid tree is required to clean up pid from not terminated
		childs tree, but it needs to be done exactly once as rb tree
		implementation is not guarded against double removal. Erasing or
		adding same element multiple times, leads to malformed red-black tree
		and segmentation faults. This patch removes double erase in described
		scenario.
	    build: fix compilation failure if building without VMACs.
	    vrrp: fix reading of iproute2 conf files when directories don’t exist.
	    vrrp: fix segfault when instance has no interface configured. If a vrrp
		instance has no interface configured (so it is unicast), processing
		SIGUSR1 resulted ina segfault.
	    vrrp: Don’t segfault if open_sockpool_socket() fails to open sockets. If a
		unicast VRRP instance is configured and the unicast_src_ip does not
		exist on the system, then the bind() fails and the sockets are not
		opened. This commit ensures that in that case vrrp->sockets is not
		dereferenced. This is not a real fix to the problem. We need to track
		the addition and removal of unicast_src_ip addresses, and enter fault
		state if the address in not configured, or when it is removed.
	    vrrp: interface add should call setup_interface(). When an interface is
		(re-)added, setup_interface() should be called even if vrrp->flags is
		set (eg VRRP_FLAG_NOPREEMPT).
	    vrrp: fix recreating a VMAC interface with IPv6. The sin6_scope_id was not
		being updated if a VMACs underlying interface were deleted and
		recreated, causing the bind() call to fail. This commit now correctly
		updates the sin6_scope_id field in mcast_daddr.
	    vrrp: fix persistent FAULT state with use_vmac when interfaces renamed. If
		an existing base interface of a VMAC is renamed, delete the VMAC since
		the configure base interface no longer exists. When an existing
		interface is renamed to match the base interface for a VMAC for a VRRP
		instance, for IPv6 when the VMAC interface is created a link local
		address is added, so clear the NO_ADDRESS fault flag by calling
		try_up_instance(). For IPv4 we do not add an address to the VMAC when
		it is created, so will wait for notlink notifications of addresses on
		the base interface, which can then be added to be VMAC.
	    vrrp: fix keepalived warning of ipsets specified without iptables.
		keepalived was warning that using ipsets had been specified but
		iptables had not been specified, even if ipsets had not been specified.
    2.3.2
	New
	    all: add –ignore-sigint option. This is needed for running keepalived
		under GDB (see https://bugzilla.kernel.org/show_bug.cgi?id=9039#c8).
	    vrrp: allow specifing interval amd timeout to milli-second resolution.
		Although running track_scripts too rapidly can have use cause heavy
		system load, there are use cases for being able to run scripts more
		frequently than 1 second, and also at intervals not in whole seconds.
		This commit adds the option to be able to specify the interval and
		timeout timers to a resolution in milli-seconds.
	Improvements
	    vrrp: remove need for route to have configured interface to track it. If a
		virtual route did not have an interface configured, keepalived would
		log a warning saying that it could not track the route, and then would
		disable tracking of that route. It appears that it is not necessary to
		know the interface in order to track the route, and in any event the
		netlink message received after adding the route identifies the
		interface for the route if it is appropriate. So this commit removes
		the requirement to specify an interface in order to track a route.
	    intall: Update INSTALL instructions - add openSUSE.
	    ipvs: Retry ipvs_nl_send_message() in ipvs_getinfo(). If we have to call
		keepalived_modprobe() for the ip_vs module, on some distros (e.g.
		RHEL based ones but not Fedora) we need to call ipvs_nl_send_message()
		twice in ipvs_getinfo(), since the first call fails. On most distros
		keepalived_modprobe() does not need to be called, since calling
		genl_ctrl_resolve(sock, IPVS_GENL_NAME) loads the ip_vs module.
	    core: improve error message for process event listen.
	    all: Properly handle an include file name ending with ‘’.
	    vrrp: Allow for Ethernet frame padding for short packets. Some network
		interface cards do not strip Ethernet frame padding before passing a
		packet to userspace (recvmesg()). keepalived checks the received
		packet length but wasn’t allowing for extra bytes to be received that
		were added as frame padding. This commit allows for frame padding to
		be received and not report an incorrect packet length.
	    vrrp: Remove duplicate dumping of master advert interval. Don’t write
		master advert interval in keepalived.data twice when using VRRPv3 and
		the VRRP instance is in backup state.
	    vrrp: Handle empty ipset names with vrrp_ipsets keyword. We now handle
		empty ipset names and return a config error.
	    vrrp: handle empty iptables chain names - vrrp_iptables keyword. We now
		return an error if a chain name is empty.
	    vrrp-ipvs: handle empty nftables chain names. We now return an error if a
		chain name is empty.
	    vrrp: use configured vrrp ipset names rather than ignore them.
	    vrrp: check configured vrrp ipset names are all different. If a pair of
		configured ipset names are the same, there will be an error when using
		the ipsets. This commits checks and logs an error if two ipset names
		are the same.
	    core: remove some duplicate include files.
	    core: ensure only one instance of keepalived can run per config_id. There
		was a window when keepalived starts up when if two (or more) instances
		were starting at the same time, they might not detect the other
		instance is running. This commit add advisort file locking on the PID
		files to ensure that only one instance can run at a time.
	    vrrp: Duplicate/drop MLDv1 listener reports on VMACs. MLDv2 listener
		reports were being handled, but not MLDv1. This commit now adds
		handling of MLDv1 listener reports as well.
	    all: Ensure pid file exists when respawning child process. If a child
		process is respawned, the old pidfile may or may not still exist. If
		it doesn’t exist, we need to recreate it. If it still exists we need
		to reset our file offset and truncate the file before re-wrighting it.
	    all: better pidfile handling after reload.
	    vrrp: add thread_timer_expired keyword as a synonym of
		timer_expired_backup. The release notes referred to
		thread_timer_expired, so it is added for completeness but logs a
		message to change the keyword to timer_expired_backup.
	    bfd: use time_t to avoid implicit ptr type casting. This fixes an
		incompatible pointer type [-Wincompatible-pointer-types] issue when
		compiling keepalived with GCC 14 [1] in 32-bit architectures where
		time_t size is 64 bits.
	    vrrp-ipvs: Stop setting SO_LINGER on TCP sockets. Setting SO_LINGER causes
		the close() call to block until the first of: 1. the ACK of the FIN is
		received 2. the SO_LINGER timeout expires Since the SO_LINGER timeout
		was set to 5 seconds, if the FIN or the subsequent ACK were lost, then
		keepalived would block for 5 seconds, which must not be allowed to
		happen. The only TCP sockets that keepalived opens are for TCP_CHECK,
		HTTP_GET, SSL_GET, SMTP_CHECK and sending notify emails. For all of
		these, for any data that keepalived sends it receives data in
		response, and so there is no purpose in using SO_LINGER. Removing
		setting SO_LINGER will stop the occasional ‘A thread timer expired
		5.1nnnnn seconds ago’, as reported in issue #2271.
	    all: use correct format specifier for time fields. 32 bit Debian uses a 32
		bit TIMESIZE, whereas 32 bit Ubuntu uses a 64 bit TIMESIZE. This means
		that on 32 bit Ubuntu some time types need to be printed using “%lld”,
		whereas on 32 bit Debian, and on 64 bit systems “%ld” is what is
		needed. Using the wrong format specifier was causing compilation
		warnings on 32 bit Debian. The issue impacts printing time_t, struct
		timeval tv_sec and tv_usec and struct timespec tv_sec fields.
		Peversely, on a 32 bit system when TIMESIZE is 64, struct timeval
		tv_usec is 64 bits, whereas struct timesec tv_nsec is 32 bits. The
		commit adds configure time checking of the right format specifiers to
		use, and adds definitions PRI_time_t, PRI_tv_sec, PRI_ts_sec etc.
	    core: update addattr_l to match current iproute2 code - almost. The
		alignment calculations were not coerect, so this commit updates
		addattr_l to match the iproute2 version, EXCEPT there appears to be 1
		issue in the iproute2 code when NLMSG_ALIGN is used when RTA_ALIGN
		should be used. The difference is entirely cosmetic (at the moment)
		since the functionality of the 2 macros is currently identical.
	    lib: add micro-second timers to memory allocation debugging. Previously
		the time was logged for memory allocation/freeing operations in
		seconds. When comparing when memory was allocated/freed to debugging
		logging via a log file, it was helpful, in terms of being able to
		identify the sequence of events, to have the time of memory
		allocations etc logged in micro-seconds.
	    vrrp: on reload only configured track_script name was checked. On a
		reload, only the configured name of a track_script was being checked
		to see if the new config track_script matched the old config
		track_script. If the script to be executed were changed, but the
		configured named of the script were kept the same, then the status of
		the old script would be transferred to the new script, despite the
		scripts being completely different. This commit now checks that the
		script really is the same, in terms of the path, parameters and user
		executing the script.
	    vrrp: On reload with addresses added to VRRP instance send 2nd GARPs. If
		garp_master_delay is non zero, then after a reload when VIPs are added
		to a VRRP instance in master state, as well as the initial block of
		GARP messages that are sent, the messages need to be repeated after
		garp_master_delay seconds. This commit adds sending the second block.
	    vrrp: merge vrrp instance garp_pending and gna_pending flags. Combine
		garp_pending and gna_pending flags into a single flags; that is all
		that is necessary and simplifies the code.
	    vrrp: Use timer threads for delayed sending of GARPs/GNAs. Previously
		whenever a VRRP instance send an advert, it checked to see if any more
		GARPs/GNAs were due to be sent, either for garp_master_delay or
		garp_master_refresh. Using timer threads removes the checking every
		time an advert is sent, and the relevant code is only triggered when a
		timer expires.
	    vrrp: stop using alloc_strvec() for parsing rttables files. It was a good
		idea at the time, but is not really appropriate. The parsing can be
		done just as simply without using alloc_strvec().
	    all: stop “unmatched quotes” warning for quoted strings. If a line with a
		quoted string has unbalanced quote characters when parsed as a
		standard (not quoted) string, an innapropriate warning was issued for
		unmatches quotes. This commit now stops the warning. This commit is
		not elegant, and it would be appreciated if a neater solution could be
		found. If anyone has a better solution, please submit a pull request
		or raise an issue explaining the solution.
	    all: change checking process name at reload to include not NULL checks.
		The code was using the reload variable as an indicator that
		prev_global_data was not NULL, and this was causing some static code
		analysers to to flag up NULL pointer dereferences. The patch
		explicitly checks whether prev_global_data is NULL or not, since this
		is synonymous with testing the reload variable.
	    all: clear pointers to old data structures freed after reload. This means
		that if that if there is a subsequent reference to the old data via
		thoe old_global_data, or old{bfd,check,vrrp} pointers, it should cause
		a segfault rather than undefined behaviour. It will also make it more
		straightford to debug any problem should it occur.
	    vrrp: update location of iproute config files. Since iproute2 version 3.3
		the location of the config files has been configurable, with the
		default being /etc/iproute2. Since version 4.4 there has been an
		rt_tables.d sub-directory. Version 4.10 added an rt_protos.d
		sub-directory, and version 6.5 added a second directory
		(/usr/lib/iproute2 or /usr/lib64/iproute) which 6.7 changed to
		/usr/share/iproute2 as the default. No major distro appears to change
		the default locations, and the only distro that used verion 6.5 or 6.6
		was Fedora 40, but that has now upgraded to 6.7 so we are not bothered
		with the /usr/lib* options. The two directories have configure
		options, and if they are not specified, configure attempts to get the
		locations from the ip-route man page or the ip executable.
	    vrrp: Specify protocol for IP addresses that keepalived adds. This is
		similar to being able to specify a protocol of ip routes and rules.
	    vrrp: Add configure option to update /etc/rt_addrprotos. If there is no
		keepalived entry in rt_addrprotos create an entry which is removed
		when keepalived terminates. This will allow ip address show to display
		the protocol of an address as “keepalived” rather than 0x12.
	    vrrp: always add a keepalived entry to rt_addrprotos is none exists.
	    doc: Some updates.
	Fixes
	    vrrp: Handle a reload before vrrp_delayed_start has expired. If
		keepalived reloaded its configuration before a specified
		vrrp_startup_delay had expired, the startup_delay was never being
		timed out, and so all received adverts would be discarded. The commit
		caused the startup_delay timer to be reinstated after a reload if the
		timer has not yet expired.
	    ipvs: Update status code of misc checker if changes while in fault state.
		The exit code of a misc checker can be read via SNMP. The misc check
		code was not updating the last exit code if the checker was not
		dynamic, the checker was already down (i.e. returned a non 0 exit
		code), and the exit code changed from the previous exit code. This
		meant that the exit code reported via SNMP was not the latest exit
		code, but the exit code that caused the status of the checker to
		change. This commit now updates the last exit code, even if the
		checker is already down.
	    vrrp: Ensure VRRPv3 advert interval strictly <= 40.95 seconds. If an
		advert interval of 40.958 seconds was configured, it was being round
		up to 40.96 after the check that the advert interval was less than
		40.96. The consequence of this was that adverts were being sent at
		40.96 second intervals, but worse, the advert interval in the VRRP
		packet was set to 0. This commit now ensures that after the rounding
		the advert interval is <= 40.95 seconds.
	    vrrp: fix track process reinitialize fork delay timer. Github user
		Bbulatov identified that terminate_delay was being used when
		fork_delay should have been used. While investigating, it was also
		found, albeit in a debug message that fork_delay was used where
		terminate_delay should have been used. Further, the process state was
		being updated immediately even if the fork_delay was being invoked.
	    vrrp: fix memory leak if error in vrrp_ipsets configuration.
	    vrrp: stop memory leak when error in configuring vrrp_iptables.
	    bfd: make alloc_bfd() return NULL rather than false on error. alloc_bfd()
		returns a bfd_t *, but in the case of errors it was returning false,
		which clearly should have been NULL. This issues was identified by
		compiling with -std=c23.
	    vrrp: fix corruption of master-child_pid red black tree. Child process
		thread_t structures use two red-black trees, one for the timeout, and
		the other for pids. It is important to ensure that threads are removed
		from the child_pid RB tree at the correct time. This was not happening
		when reloads were occurring and there was a THREAD_CHILD_TIMEOUT
		thread on the ready list. A few other instances of the thread not
		being removed from the child_pid RB tree correctly, which are also
		resolved by this commit.
	    all: Fix parsing of xNN in quoted strings. Following x keepalived
		processed all following hex digits, but only returned one byte. For
		example x20file would result in a byte 0x0f followed by the string
		“ile”. This commit limits the number of hex digits consumed to 2.
	    all: fix parsing of escaped characters in quoted strings.
	    core: fix error report in json version parser.
