a/aaa_glibc-solibs-2.33-x86_64-3.txz:  Rebuilt.

l/glibc-2.33-x86_64-3.txz:  Rebuilt.
  Since glibc-2.34 makes a potentially risky change of moving all functions
  into the main library, and another inconvenient (for us) change of renaming
  the library files, we'll stick with glibc-2.33 for Slackware 15.0 and test
  the newer glibc in the next release cycle. But we'll backport the security
  fixes from glibc-2.34 with this update:
  The nameserver caching daemon (nscd), when processing a request for netgroup
  lookup, may crash due to a double-free, potentially resulting in degraded
  service or Denial of Service on the local system. Reported by Chris Schanzle.
  The mq_notify function has a potential use-after-free issue when using a
  notification type of SIGEV_THREAD and a thread attribute with a non-default
  affinity mask.
  The wordexp function may overflow the positional parameter number when
  processing the expansion resulting in a crash. Reported by Philippe Antoine.

l/glibc-profile-2.33-x86_64-3.txz:  Rebuilt.
l/liburing-2.0-x86_64-1.txz:  Added.
  This is needed by mariadb, and provides increased performance on high speed
  devices such as NVMe.
n/dovecot-2.3.16-x86_64-1.txz:  Upgraded.

+Subject: [PATCH] Fix use of __pthread_attr_copy in mq_notify (bug 27896)
+
+__pthread_attr_copy can fail and does not initialize the attribute
+structure in that case.
+
+If __pthread_attr_copy is never called and there is no allocated
+attribute, pthread_attr_destroy should not be called, otherwise
+there is a null pointer dereference in rt/tst-mqueue6.
+
+Fixes commit 42d359350510506b87101cf77202fefcbfc790cb
+("Use __pthread_attr_copy in mq_notify (bug 27896)").

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description. Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in. You must
+# make exactly 11 lines for the formatting to be correct. It's also
+# customary to leave one space after the ':'.

+liburing: setup and teardown io_uring instances, and also a simplified interface
+liburing: for applications that don't need (or want) to deal with the full
+liburing: kernel side implementation.
