2016-12-31resolv: Deprecate the "inet6" option and RES_USE_INET6 [BZ #19582]Florian Weimer2-11/+11
2016-12-21Fix nss_nisplus build with mainline GCC (bug 20978).Joseph Myers1-1/+1
glibc build with current mainline GCC fails because nis/nss_nisplus/nisplus-alias.c contains code if (name != NULL) { *errnop = EINVAL; return NSS_STATUS_UNAVAIL; } char buf[strlen (name) + 9 + tablename_len]; producing an error about strlen being called on a pointer that is always NULL (and a subsequent use of that pointer with a %s format in snprintf). As Andreas noted, the bogus conditional comes from a 1997 change: - if (name == NULL || strlen(name) > 8) - return NSS_STATUS_NOTFOUND; - else + if (name != NULL || strlen(name) <= 8) So the intention is clearly to return an error for NULL name. This patch duly inverts the sense of the conditional. It fixes the build with GCC mainline, and passes usual glibc testsuite testing for x86_64. However, I have not tried any actual substantive nisplus testing, do not have an environment for such testing, and do not know whether it is possible that strlen (name) or tablename_len might be large so that the VLA for buf is actually a security issue. However, if it is a security issue, there are plenty of other similar instances in the nisplus code (that haven't been hidden by a bogus comparison with NULL) - and nis_table.c:__create_ib_request uses strdupa on the string passed to nis_list, so a local fix in the caller wouldn't suffice anyway (see bug 20987). (Calls to strdupa and other such macros that use alloca must be considered equally questionable regarding stack overflow issues as direct calls to alloca and VLA declarations.) [BZ #20978] * nis/nss_nisplus/nisplus-alias.c (_nss_nisplus_getaliasbyname_r): Compare name == NULL, not name != NULL.
2016-09-23Installed-header hygiene (BZ#20366): Simple self-contained fixes.Zack Weinberg1-1/+1
Some headers did not include all of their prerequisite headers. * rpcsvc/nislib.h: Include rpcsvc/nis.h. * sysdeps/unix/sysv/linux/netrose/rose.h: Include sys/socket.h and netax25/ax25.h. <endian.h> only defines BYTE_ORDER, BIG_ENDIAN, LITTLE_ENDIAN, etc. under __USE_MISC; glibc's headers should use __BYTE_ORDER, __BIG_ENDIAN, __LITTLE_ENDIAN, etc. instead. * inet/netinet/icmp6.h, inet/netinet/ip6.h * resolv/arpa/nameser_compat.h: Use __BYTE_ORDER etc. instead of BYTE_ORDER etc. sys/types.h only conditionally defines caddr_t and clockid_t. * sysdeps/unix/sysv/linux/sys/quota.h: Use __caddr_t instead of caddr_t. * sysdeps/unix/sysv/linux/sys/timerfd.h: Use __clockid_t instead of clockid_t. Remove a #warning that was the sole actual problem with using sys/ipc.h without _GNU_SOURCE/_XOPEN_SOURCE. * sysvipc/sys/ipc.h: Remove unnecessary #warning. _LIBC, __USE_XOPEN2K8, and __STDC_VERSION__ are not always defined. It seems to me that _LIBC should not appear in installed headers, but avoiding that for argp specifically would require more surgery than feels appropriate for this patch set. It's possible that "#ifdef _LIBC" would be sufficient, but I wanted to be conservative. All three versions of bits/socket.h want to know whether __flexarr will produce a real flexible array member -- specifically, one that doesn't alter sizeof(the structure containing it). They were testing for this with a complicated #if condition that did not agree with sys/cdefs.h and that tripped -Wundef warnings under -std=c90. I added a new macro to sys/cdefs.h, __glibc_c99_flexarr_available, which reveals exactly what these headers want to know. I also took the opportunity to flatten the rather messy conditional nest defining __flexarr. * argp/argp.h: Check whether _LIBC is defined before expanding it. * posix/glob.h: Check whether __USE_XOPEN2K8 is defined instead of expanding it. * misc/sys/cdefs.h: Tidy up conditional nest defining __flexarr. Define __glibc_c99_flexarr_available to 1 when the compiler supports C99-compatible flexible array members, 0 otherwise. * sysdeps/unix/sysv/linux/bits/socket.h * sysdeps/mach/hurd/bits/socket.h * bits/socket.h: Use __glibc_c99_flexarr_available in definitions of struct cmsghdr and CMSG_DATA.

2015-10-06nss_nis: Do not call malloc_usable_size [BZ #10432]Florian Weimer1-1/+0

2015-09-08Move bits/libc-lock.h and bits/libc-lockP.h out of bits/ (bug 14912).Joseph Myers29-29/+29
It was noted in <https://sourceware.org/ml/libc-alpha/2012-09/msg00305.html> that the bits/*.h naming scheme should only be used for installed headers. This patch renames bits/libc-lock.h to plain libc-lock.h and bits/libc-lockP.h to plain libc-lockP.h to follow that convention. Note that I don't know where libc-lockP.h comes from for Hurd (the Hurd libc-lock.h includes libc-lockP.h, but the only libc-lockP.h in the glibc source tree is for NPTL) - some unmerged patch? - but I updated the #include in the Hurd libc-lock.h anyway. Tested for x86_64 (testsuite, and that installed stripped shared libraries are unchanged by the patch). [BZ #14912] * bits/libc-lock.h: Move to ... * sysdeps/generic/libc-lock.h: ...here.

2014-02-26Consistently include Makeconfig after defining subdir.Joseph Myers1-2/+2
In <https://sourceware.org/ml/libc-alpha/2014-01/msg00196.html> I noted it was necessary to add includes of Makeconfig early in various subdirectory makefiles for the tests-special variable settings added by that patch to be conditional on configuration information. No-one commented on the general question there of whether Makeconfig should always be included immediately after the definition of subdir. This patch implements that early inclusion of Makeconfig in each directory (which is a lot easier than consistent placement of includes of Rules). Includes are added if needed, or moved up if already present. Subdirectory "all:" targets are removed, since Makeconfig provides one. There is potential for further cleanups I haven't done. Rules and Makerules have code such as ifneq "$(findstring env,$(origin headers))" "" headers := endif to override to empty any value of various variables that came from the environment. I think there is a case for Makeconfig setting all the subdirectory variables (other than subdir) to empty to ensure no outside value is going to take effect if a subdirectory fails to define a variable. (A list of such variables, possibly out of date and incomplete, is in manual/maint.texi.) Rules and Makerules would give errors if Makeconfig hadn't already been included, instead of including it themselves. The special code to override values coming from the environment would then be obsolete and could be removed. Tested x86_64, including that installed binaries are identical before and after the patch. * argp/Makefile: Include Makeconfig immediately after defining subdir. * assert/Makefile: Likewise. * benchtests/Makefile: Likewise. * catgets/Makefile: Likewise. * conform/Makefile: Likewise. * crypt/Makefile: Likewise. * csu/Makefile: Likewise.

2010-11-22Fix multiple nss_compat initgroups() bugsUlrich Drepper1-8/+11
Compat initgroups() is completely broken; the code will always set skip_initgroups_dyn to true, so initgroups() will never be actually called, but due to the nature of the code, setgrent() won't be called either - thus, subsequent invocations of initgroups() will not return the NIS group list anymore. This is a simple patch that makes sure skip_initgroups_dyn is set only in case initgroups is not available; it also attempts to handle the unavailability of other NSS interfaces better.
