Enable --enable-fortify-source with clang

2025-11-21T16:13:11Z

clang generates internal calls for some _chk symbol, so add internal aliases for them, and stub some with rtld-stubbed-symbols to avoid ld.so linker issues. Reviewed-by: Sam James

Add _FORTIFY_SOURCE support for inet_pton

2025-03-24T18:43:03Z

Add function __inet_pton_chk which calls __chk_fail when the size of argument dst is too small. inet_pton is redirected to __inet_pton_chk or __inet_pton_warn when _FORTIFY_SOURCE is > 0. Also add tests to debug/tst-fortify.c, update the abilist with __inet_pton_chk and mention inet_pton fortification in maint.texi. Co-authored-by: Frédéric Bérat Reviewed-by: Florian Weimer

Add _FORTIFY_SOURCE support for inet_ntop

2025-03-21T08:35:42Z

- Create the __inet_ntop_chk routine that verifies that the builtin size of the destination buffer is at least as big as the size given by the user. - Redirect calls from inet_ntop to __inet_ntop_chk or __inet_ntop_warn - Update the abilist for this new routine - Update the manual to mention the new fortification Reviewed-by: Florian Weimer

Prepare inet_ntop to be fortified

Rename inet_ntop to __inet_ntop and create the inet_ntop weak alias based on it in order to prepare for disabling fortification when available. Reviewed-by: Florian Weimer

CVE-2016-10739: getaddrinfo: Fully parse IPv4 address strings [BZ #20018]

2019-01-21T20:26:03Z

The IPv4 address parser in the getaddrinfo function is changed so that it does not ignore trailing whitespace and all characters after it. For backwards compatibility, the getaddrinfo function still recognizes legacy name syntax, such as 192.000.002.010 interpreted as 192.0.2.8 (octal). This commit does not change the behavior of inet_addr and inet_aton. gethostbyname already had additional sanity checks (but is switched over to the new __inet_aton_exact function for completeness as well). To avoid sending the problematic query names over DNS, commit 6ca53a2453598804a2559a548a08424fca96434a ("resolv: Do not send queries for non-host-names in nss_dns [BZ #24112]") is needed.

Fix resolver inet_* namespace (bug 17722).

2014-12-17T18:09:11Z

Parts of the resolver brought in by pthreads (at least) use inet_* functions that aren't in the 1995/6 edition of POSIX that introduced pthreads (or in one case, use __inet_aton which is then defined in the same file as non-weak inet_addr). This patch fixes this by making the affected functions into weak alias for __inet_* and using those names in the problematic resolver code. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). [BZ #17722] * inet/inet_mkadr.c (inet_makeaddr): Rename to __inet_makeaddr and define as weak alias of __inet_makeaddr. * resolv/inet_addr.c (inet_addr): Rename to __inet_addr and define as weak alias of __inet_addr. * resolv/inet_pton.c (inet_pton): Rename to __inet_pton and define as weak alias of __inet_pton. Use libc_hidden_weak. * include/arpa/inet.h (__inet_pton): Declare. Use libc_hidden_proto. (inet_makeaddr): Don't use libc_hidden_proto. (__inet_makeaddr): Declare. Use libc_hidden_proto. * resolv/res_init.c (__res_vinit): Use __inet_pton instead of inet_pton. Use __inet_makeaddr instead of inet_makeaddr. * conform/Makefile (test-xfail-POSIX/pthread.h/linknamespace): Remove variable. (test-xfail-POSIX/sched.h/linknamespace): Likewise. (test-xfail-POSIX/time.h/linknamespace): Likewise.
