like the other tty ioctls that we only warn about). Do the main
ioctl (tcgetattr) first, since that provides a better error message
(ENOTTY instead of EINVAL).

Suppress SIGTTOU when handling errors
Calls to error () can cause SIGTTOU to send gdb to the background.
For example, on an Arm build:
(gdb) b main
Breakpoint 1 at 0x10774: file /build/gdb/testsuite/../../../src/binutils-gdb/gdb/testsuite/gdb.base/watchpoint.c, line 174.
(gdb) r
Starting program: /build/gdb/testsuite/outputs/gdb.base/watchpoint/watchpoint
[1]+ Stopped ../gdb ./outputs/gdb.base/watchpoint/watchpoint
localhost$ fg
../gdb ./outputs/gdb.base/watchpoint/watchpoint
Cannot parse expression `.L1199 4@r4'.
warning: Probes-based dynamic linker interface failed.
Reverting to original interface.
The SIGTTOU is raised whilst inside a syscall during the call to tcdrain.
Fix is to use scoped_ignore_sigttou to ensure SIGTTOU is blocked.
In addition fix include comments - job_control is not included via terminal.h
gdb/ChangeLog:
* event-top.c: Remove include comment.
* inflow.c (class scoped_ignore_sigttou): Move from here...
* inflow.h (class scoped_ignore_sigttou): ...to here.
* ser-unix.c (hardwire_drain_output): Block SIGTTOU during drain.
* top.c: Remove include comment.
init command works:
- document it
- calculate the checksum instead of hardcoding it, so the init command can be
easily changed
- drop the first init string - it's entirely overwritten by the 2nd
- remove some debug goop

Decorate struct in6_addr with the __packed attribute
This avoids undefined behavior when accessing misaligned pointers.

Patch by Akul Pillai.
----------------------------
This change caused regression in at least qemu and addresses potential binary ABI breakage.
Fixes PR/54523 by <gson>
5277. [bug] Cache DB statistics could underflow when serve-stale
was in use, because of a bug in counter maintenance
when RRsets become stale.
Functions for dumping statistics have been updated
to dump active, stale, and ancient statistic
counters. Ancient RRset counters are prefixed
with '~'; stale RRset counters are still prefixed
with '#'. [GL #602]
5275. [bug] Mark DS records included in referral messages
with trust level "pending" so that they can be
validated and cached immediately, with no need to
re-query. [GL #964]
5274. [bug] Address potential use after free race when shutting
down rpz. [GL #1175]
5273. [bug] Check that bits [64..71] of a dns64 prefix are zero.
[GL #1159]
5269. [port] cygwin: can return ETIMEDOUT on connect() with a
non-blocking socket. [GL #1133]
5268. [bug] named could crash during configuration if
configured to use "geoip continent" ACLs with
legacy GeoIP. [GL #1163]
5266. [bug] named-checkconf failed to report dnstap-output
missing from named.conf when dnstap was specified.
[GL #1136]
5265. [bug] DNS64 and RPZ nodata (CNAME *.) rules interacted badly
[GL #1106]
5264. [func] New DNS Cookie algorithm - siphash24 - has been added
to BIND 9. [GL #605]
5236. [func] Add SipHash 2-4 implementation in lib/isc/siphash.c
and switch isc_hash_function() to use SipHash 2-4.
[GL #605]
--- 9.14.4 released ---
5260. [bug] dnstap-read was producing malformed output for large
packets. [GL #1093]
5258. [func] Added support for the GeoIP2 API from MaxMind,
when BIND is compiled using "configure --with-geoip2".
The legacy GeoIP API can be enabled by using
"configure --with-geoip" instead. These options
cannot be used together.
Certain geoip ACL settings that were available with
legacy GeoIP are not available when using GeoIP2.
See the ARM for details. [GL #182]
5257. [bug] Some statistics data was not being displayed.
Add shading to the zone tables. [GL #1030]
5256. [bug] Ensure that glue records are included in root
priming responses if "minimal-responses" is not
set to "yes". [GL #1092]
5255. [bug] Errors encountered while reloading inline-signing
zones could be ignored, causing the zone content to
be left in an incompletely updated state rather than
reverted. [GL #1109]
5254. [func] Collect metrics to report to the statistics-channel
DNSSEC signing operations (dnssec-sign) and refresh
operations (dnssec-refresh) per zone and per keytag.
[GL #513]
5253. [port] Support platforms that don't define ULLONG_MAX.
[GL #1098]
5251. [bug] Statistics were broken in x86 Windows builds.
[GL #1081]
5249. [bug] Fix a possible underflow in recursion clients
statistics when hitting recursive clients
soft quota. [GL #1067]
--- 9.14.3 released ---
5244. [security] Fixed a race condition in dns_dispatch_getnext()
that could cause an assertion failure if a
significant number of incoming packets were
rejected. (CVE-2019-6471) [GL #942]
5243. [bug] Fix a possible race between dispatcher and socket
code in a high-load cold-cache resolver scenario.
[GL #943]
5242. [bug] In relaxed qname minimizatiom mode, fall back to
normal resolution when encountering a lame
delegation, and use _.domain/A queries rather
than domain/NS. [GL #1055]
5241. [bug] Fix Ed448 private and public key ASN.1 prefix blobs.
[GL #225]
5240. [bug] Remove key id calculation for RSAMD5. [GL #996]
5238. [bug] Fix a possible deadlock in TCP code. [GL #1046]
5237. [bug] Recurse to find the root server list with 'dig +trace'.
[GL #1028]
5234. [port] arm: just use the compiler's default support for
yield. [GL #981]
--- 9.14.2 released ---
5233. [bug] Negative trust anchors did not work with "forward only;"
to validating resolvers. [GL #997]
5231. [protocol] Add support for displaying CLIENT-TAG and SERVER-TAG.
[GL #960]
5229. [protocol] Enforce known SSHFP fingerprint lengths. [GL #852]
5228. [cleanup] If trusted-keys and managed-keys are configured
simultaneously for the same name, the key cannot
be rolled automatically. This configuration now
logs a warning. [GL #868]
5224. [bug] Only test provide-ixfr on TCP streams. [GL #991]
5223. [bug] Fixed a race in the filter-aaaa plugin accessing
the hash table. [GL #1005]
5222. [bug] 'delv -t ANY' could leak memory. [GL #983]
5221. [test] Enable parallel execution of system tests on
Windows. [GL !4101]
5220. [cleanup] Refactor the isc_stat structure to take advantage
of stdatomic. [GL !1493]
5219. [bug] Fixed a race in the filter-aaaa plugin that could
trigger a crash when returning an instance object
to the memory pool. [GL #982]
5218. [bug] Conditionally include <dlfcn.h>. [GL #995]
5217. [bug] Restore key id calculation for RSAMD5. [GL #996]
5216. [bug] Fetches-per-zone counter wasn't updated correctly
when doing qname minimization. [GL #992]
5215. [bug] Change #5124 was incomplete; named could still
return FORMERR instead of SERVFAIL in some cases.
[GL #990]
5214. [bug] win32: named now removes its lock file upon shutdown.
[GL #979]
5213. [bug] win32: Eliminated a race which allowed named.exe running
as a service to be killed prematurely during shutdown.
[GL #978]
5211. [bug] Allow out-of-zone additional data to be included
in authoritative responses if recursion is allowed
and "minimal-responses" is disabled. This behavior
was inadvertently removed in change #4605. [GL #817]
5210. [bug] When dnstap is enabled and recursion is not
available, incoming queries are now logged
as "auth". Previously, this depended on whether
recursion was requested by the client, not on
whether recursion was available. [GL #963]
5209. [bug] When update-check-ksk is true, add_sigs was not
considering offline keys, leaving record sets signed
with the incorrect type key. [GL #763]
5208. [test] Run valid rdata wire encodings through totext+fromtext
and tofmttext+fromtext methods to check these methods.
[GL #899]
5207. [test] Check delv and dig TTL values. [GL #965]
5206. [bug] Delv could print out bad TTLs. [GL #965]
5205. [bug] Enforce that a DS hash exists. [GL #899]
5204. [test] Check that dns_rdata_fromtext() produces a record that
will be accepted by dns_rdata_fromwire(). [GL #852]
5203. [bug] Enforce whether key rdata exists or not in KEY,
DNSKEY, CDNSKEY and RKEY. [GL #899]
5202. [bug] <dns/ecs.h> was missing ISC_LANG_ENDDECLS. [GL #976]
5190. [bug] Ignore trust anchors using disabled algorithms.
[GL #806]
