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 (A list of such variables, possibly out of date and incomplete, is in manual/maint.texi.)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.

2014-02-10Use glibc_likely instead __builtin_expect.Ondřej Bílka1-1/+1
2014-01-27Fix invalid memory access when parsing netgroup files with blank lines (BZ ↵Siddhesh Poyarekar1-1/+2
#16506) The netgroups file parsing code tries to access the character before the newline in parsed lines to see if it is a backslash (\). This results in an access before the block allocated for the line if the line is blank, i.e. does not have anything other than the newline character. This doesn't seem like it will cause any crashes because the byte belongs to the malloc metadata block and hence access to it will always succeed. There could be an invalid alteration in code flow where a blank line is seen as a continuation due to the preceding byte *happening* to be '\\'. This could be done by interposing malloc, but that's not really a security problem since one could interpose getnetgrent_r itself and achieve a similar 'exploit'. The possibility of actually exploiting this is remote to impossible since it also requires the previous line to end with a '\\', which would happen only on invalid configurations.

H_ERRNO_ARGS is unnecessary since we this file is specifically for hosts lookup.
2013-11-28Get canonical name in getaddrinfo from hosts file for AF_INET (fixes 16077)Siddhesh Poyarekar2-250/+258
AF_INET lookup in hosts file uses _nss_files_gethostbyname2_r, which is not capable of returning a canonical name if it has found one. This change adds _nss_files_gethostbyname3_r, which wraps around _nss_files_gethostbyname2_r and then returns result.h_name as the canonical name.
2013-11-07Make getent services compliant with RFC 6335 section 5.1 Fixes bug 15374Ondřej Bílka1-2/+6
The RFC 6335 allows services that start with digit (like 3com-tsmux). These were parsed as port number which this patch fixes.
2013-10-30Fix reads for sizes larger than INT_MAX in AF_INET lookupSiddhesh Poyarekar1-8/+51
Currently for AF_INET lookups from the hosts file, buffer sizes larger than INT_MAX silently overflow and may result in access beyond bounds of a buffer. This happens when the number of results in an AF_INET lookup in /etc/hosts are very large. There are two aspects to the problem. One problem is that the size computed from the buffer size is stored into an int, which results in overflow for large sizes. Additionally, even if this size was expanded, the function used to read content into the buffer (fgets) accepts only int sizes. As a result, the fix is to have a function wrap around fgets that calls it multiple times with int sizes if necessary.

2013-05-21Set EAI_SYSTEM only when h_errno is NETDB_INTERNALSiddhesh Poyarekar1-4/+4
Fixes BZ #15339. NSS_STATUS_UNAVAIL may mean that a necessary input resource is not available. This could occur in a number of cases including when the network is down, system runs out of file descriptors, etc. The correct differentiator in such a case is the h_errno, which gives the nature of failure. In case of failures other than a simple 'not found', we set h_errno as NETDB_INTERNAL and let errno be the identifier for the exact error.

2012-10-30Suppress incorrect link warnings for NSS symbolsChris Metcalf5-6/+14
When glibc is built with --enable-static-nss, the warning that using NSS symbols requires the nss shared objects to be present is no longer true, as those symbols are built into libc. Suppress the warning for those symbols by providing a new macro (nss_interface_function) for the NSS functions that is defined as static_link_warning in the normal case, and empty for static NSS.
