-Subject: [PATCH] elf: Check for empty tokens before dynamic string token
- expansion [BZ #22625]
-
-The fillin_rpath function in elf/dl-load.c loops over each RPATH or
-RUNPATH tokens and interprets empty tokens as the current directory
-("./"). In practice the check for empty token is done *after* the
-dynamic string token expansion. The expansion process can return an
-empty string for the $ORIGIN token if __libc_enable_secure is set
-or if the path of the binary can not be determined (/proc not mounted).
-
-Fix that by moving the check for empty tokens before the dynamic string
-token expansion. In addition, check for NULL pointer or empty strings
-return by expand_dynamic_string_token.
-
-The above changes highlighted a bug in decompose_rpath, an empty array
-is represented by the first element being NULL at the fillin_rpath
-level, but by using a -1 pointer in decompose_rpath and other functions.
-
-Changelog:
- [BZ #22625]
- * elf/dl-load.c (fillin_rpath): Check for empty tokens before dynamic
- string token expansion. Check for NULL pointer or empty string possibly
- returned by expand_dynamic_string_token.
- (decompose_rpath): Check for empty path after dynamic string
- token expansion.

-Subject: [PATCH] Fix integer overflow in malloc when tcache is enabled [BZ
- #22375]
-
-When the per-thread cache is enabled, __libc_malloc uses request2size (which
-does not perform an overflow check) to calculate the chunk size from the
-requested allocation size. This leads to an integer overflow causing malloc
-to incorrectly return the last successfully allocated block when called with
-a very large size argument (close to SIZE_MAX).
-
-This commit uses checked_request2size instead, removing the overflow.
-
