+Subject: [PATCH 2/3] credentials: Invalid Linux struct ucred means "no
+ information"
+
+On Linux, if getsockopt SO_PEERCRED is used on a TCP socket, one
+might expect it to fail with an appropriate error like ENOTSUP or
+EPROTONOSUPPORT. However, it appears that in fact it succeeds, but
+yields a credentials structure with pid 0, uid -1 and gid -1. These
+are not real process, user and group IDs that can be allocated to a
+real process (pid 0 needs to be reserved to give kill(0) its documented
+special semantics, and similarly uid and gid -1 need to be reserved for
+setresuid() and setresgid()) so it is not meaningful to signal them to
+high-level API users.
+
+An API user with Linux-specific knowledge can still inspect these fields
+via g_credentials_get_native() if desired.
+
+Similarly, if SO_PASSCRED is used to receive a SCM_CREDENTIALS message
+on a receiving Unix socket, but the sending socket had not enabled
+SO_PASSCRED at the time that the message was sent, it is possible
+for it to succeed but yield a credentials structure with pid 0, uid
+/proc/sys/kernel/overflowuid and gid /proc/sys/kernel/overflowgid. Even
+if we were to read those pseudo-files, we cannot distinguish between
+the overflow IDs and a real process that legitimately has the same IDs
+(typically they are set to 'nobody' and 'nogroup', which can be used
+by a real process), so we detect this situation by noticing that
+pid == 0, and to save syscalls we do not read the overflow IDs from
+/proc at all.
+
+This results in a small API change: g_credentials_is_same_user() now
+returns FALSE if we compare two credentials structures that are both
+invalid. This seems like reasonable, conservative behaviour: if we cannot
+prove that they are the same user, we should assume they are not.
+
+(Dropped new translatable string when backporting to `glib-2-62`.)
