Subject: [PATCH 0698/1095] Fix giomodule.cache being wrongly considered stale
In ostree based systems, such as flatpak and fedora silverblue, the
time of modification of every system file is epoch 0, including
giomodule.cache, which means that every module is loaded and unloaded
every time.
The solution is to use the change time of the file as well. In a typical
system, it is equal to the mtime, and in an ostree based system, since
the directory is mounted as read-only, the user cannot add a module and
we must assume that the cache file corresponds to the modules.

Subject: [PATCH 1022/1095] Fix the 6-days-until-the-end-of-the-month bug
The addition causes the date to shift
forward into 1st of the next month, because a 0-based offset
is compared to be "more than" the days in the month instead of "more than
or equal to".
This is triggered by corner-cases where transition date is 6 days
off the end of the month and our calculations put it at N+1th day of the
month (where N is the number of days in the month). The subtraction should
be triggered to move the date back a week, putting it 6 days off the end;
for example, October 25 for CET DST transition; but due to incorrect comparison
the date isn't shifted back, we add 31 days to October 1st and end up
at November 1st).
Fixes issue #2215.

`base` can be `-1` in some situations, which would lead to pointing
outside an allocation area if the sums were evaluated as `(file_name +
base) + 1` rather than `file_name + (base + 1)`.
I don’t see how this can practically cause an issue, as the arithmetic
is all finished before anything’s dereferenced, but let’s keep to the
letter of the C standard to avoid this coming up in code audits in
future.
Fix suggested by fablhx.

Subject: [PATCH] glib: ensure consistent abort-on-OOM with g_vasprintf & its
callers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The g_vasprintf method is called by g_strdup_vprintf, g_strdup_printf,
g_string_append_vprintf and more. It has three different implementations
depending on what the build target platform supports:
1. The gnulib impl appears to use the system malloc, but a
'#define malloc g_malloc' causes it to use GLib's wrapper
and thus abort on OOM. This mostly gets used on Windows
platforms or UNIX platforms with broken printf formatting.
2. The main impl mostly used on modern Linux/UNIX calls the
system vasprintf which uses the system malloc and does not
abort on OOM.
3. The final impl used on remaining platforms calls system
vsprintf on a buffer allocated by g_new, and thus always
aborts on OOM.
Of note is that impl 2 (using vasprintf) historically could abort on
OOM, if the application had installed a non-system malloc impl with
GLib. This was because the code would g_strndup the result from
vasprintf() in that scenario. This was removed in:
commit a3660532535f92cfac136435579ed4f23231f48c

Date: Fri Aug 7 09:46:49 2015 -0400
glib: remove deprecated g_mem_is_system_malloc() check in gprintf.c
Having inconsistent OOM behaviour for the three impls is undesirable and
aborting on OOM is normal pratice for GLib APIs. Thus we must thus ensure
this happens in all impls of g_vasprintf.

Unfortunately, that commit neglected to remove handlers from
g_signal_connect_object calls from the hash table that are
disconnected implicitly when the associated object goes away.
This commit addresses that bug by changing the closure invalidate
handler associated with the signal connection to properly remove the
handler from the hash table.

Subject: [PATCH 0990/1095] gsocketclient: Crash on error if error is missing
We should never return unknown errors to the application. This would be
a glib bug.
I don't think it's currently possible to hit these cases, so asserts
should be OK. For this to happen, either (a) a GSocketAddressEnumerator
would have to return NULL on its first enumeration, without returning an
error, or (b) there would have to be a bug in our GSocketClient logic.
Either way, if such a bug were to exist, it would be better to surface
it rather than hide it.
These changes are actually going to be effectively undone in a
subsequent commit, as I'm refactoring the error handling, but the commit
history is a bit nicer with two separate commits, so let's go with two.

Subject: [PATCH 0989/1095] gsocketclient: emit RESOLVING/RESOLVED events only
once
GSocketAddressEnumerator encapsulates the details of how DNS happens, so
we don't have to think about it. But we may have taken encapsulation a
bit too far, here. Usually, we resolve a domain name to a list of IPv4
and IPv6 addresses. Then we go through each address in the list and try
to connect to it. Name resolution happens exactly once, at the start.
It doesn't happen each time we enumerate the enumerator. In theory, it
*could*, because we've designed these APIs to be agnostic of underlying
implementation details like DNS and network protocols. But in practice,
we know that's not really what's happening. It's weird to say that we
are RESOLVING what we know to be the same name multiple times. Behind
the scenes, we're not doing that.
This also fixes #1994, where enumeration can end with a RESOLVING event,
even though this is supposed to be the first event rather than the last.
I thought this would be hard to fix, even requiring new public API in
GSocketAddressEnumerator to peek ahead to see if the next enumeration is
going to return NULL. Then I decided we should just fake it: always emit
both RESOLVING and RESOLVED at the same time right after each
enumeration. Finally, I realized we can emit them at the correct time if
we simply assume resolving only happens the first time. This seems like
the most elegant of the possible solutions.
Now, this is a behavior change, and arguably an API break, but it should
align better with reasonable expectations of how GSocketClientEvent
ought to work. I don't expect it to break anything besides tests that
check which order GSocketClientEvent events are emitted in. (Currently,
libsoup has such tests, which will need to be updated.) Ideally we would
have GLib-level tests as well, but in a concession to pragmatism, it's a
lot easier to keep network tests in libsoup.

Subject: [PATCH 1035/1095] gsocketclient: fix crash when async connection step
fails
This is a regression from !1686. The tmp_error is no longer valid after
it is "considered" and cannot be used at this point. We should print the
error earlier instead.

Subject: [PATCH 0991/1095] gsocketclient: return best errors possible
Originally, GSocketClient returned whatever error occured last. Turns
out this doesn't work well in practice. Consider the following case:
DNS returns an IPv4 and IPv6 address. First we'll connect() to the
IPv4 address, and say that succeeds, but TLS is enabled and the TLS
handshake fails. Then we try the IPv6 address and receive ENETUNREACH
because IPv6 isn't supported. We wind up returning NETWORK_UNREACHABLE
even though the address can be pinged and a TLS error would be more
appropriate. So instead, we now try to return the error corresponding
to the latest attempted GSocketClientEvent in the connection process.
TLS errors take precedence over proxy errors, which take precedence
over connect() errors, which take precedence over DNS errors.
In writing this commit, I made several mistakes that were caught by
proxy-test.c, which tests using GSocketClient to make a proxy
connection. So although adding a new test to ensure we get the
best-possible error would be awkward, at least we have some test
coverage for the code that helped avoid introducing bugs.
Fixes #2211

Subject: [PATCH 0985/1095] gsocketclient: set IP_BIND_ADDRESS_NO_PORT if
binding to local address
The linux kernel does not know that the socket will be used
for connect or listen and if you bind() to a local address it must
reserve a random port (if port == 0) at bind() time, making very easy
to exhaust the ~32k port range, setting IP_BIND_ADDRESS_NO_PORT tells
the kernel to choose random port at connect() time instead, when the
full 4-tuple is known.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
If the old value is destroyed before updating the TLS value in pthreads
(or the Windows equivalent) then there’s a risk of infinite recursion if
`g_private_replace()` is called from within the `GDestroyNotify`.
Avoid that by destroying the old value after doing the TLS update.
Thanks to Matthias Clasen for diagnosing the issue.

Subject: [PATCH 0734/1095] gtimezone: support footers in TZif files
Since tzcode95f (1995), TZif files have had a trailing
TZ string, used for timestamps after the last transition.
This string is specified in Internet RFC 8536 section 3.3.
init_zone_from_iana_info has ignored this string, causing it
to mishandle timestamps past the year 2038. With zic's new -b
slim flag, init_zone_from_iana_info would even mishandle current
timestamps. Fix this by parsing the trailing TZ string and adding
its transitions.
Closes #2129
