* Fix failing nss/tst-nss-files-hosts-long.Stefan Liebler2021-07-121-0/+0
| | | | | | | | | | | | | | Sometimes the test nss/tst-nss-files-hosts-long is failing as getent fails with exit-code 2. This happens if tst-reload1 was run just before this test: make t=nss/tst-reload1 test make t=nss/tst-nss-files-hosts-long test Then the test fails as /etc/nsswitch.conf contains "hosts: test2" and the hosts are not searched in /etc/hosts at all. Thus this patch just requests a post cleanup after nss/tst-reload1 has run.

* Annotate additional APIs with GCC attribute access.Martin Sebor2021-05-061-2/+5
| | | | | | | | | | | | | | | | This change continues the improvements to compile-time out of bounds checking by decorating more APIs with either attribute access, or by explicitly providing the array bound in APIs such as tmpnam() that expect arrays of some minimum size as arguments. (The latter feature is new in GCC 11.) The only effects of the attribute and/or the array bound is to check and diagnose calls to the functions that fail to provide a sufficient number of elements, and the definitions of the functions that access elements outside the specified bounds. (There is no interplay with _FORTIFY_SOURCE here yet.) Tested with GCC 7 through 11 on x86_64-linux.
* nss: fix nss_database_lookup2's alternate handling [BZ #27416]DJ Delorie2021-03-0928-96/+248
| | | | | | | | | | | | | | | | | | | | __nss_database_lookup2's extra arguments were left unused in the nsswitch reloading patch set; this broke compat (default config ignored) and shadow files (secondary name ignored) which relies on these fallbacks. This patch adds in the previous behavior by correcting the initialization of the database list to reflect the fallbacks. This means that the nss_database_lookup2 interface no longer needs to be passed the fallback info, so API and callers were adjusted. Since all callers needed to be edited anyway, the calls were changed from __nss_database_lookup2 to the faster __nss_database_get. This was an intended optimization which was deferred during the initial lookup changes to avoid touching so many files. The test case verifies that compat targets work (passwd) and that the default configuration works (group). Tested on x86-64.
* nss: Re-enable NSS module loading after chroot [BZ #27389]DJ Delorie2021-03-026-8/+32
| | | | | | | | | | | | | | | | | | | | | The glibc 2.33 release enabled /etc/nsswitch.conf reloading, and to prevent potential security issues like CVE-2019-14271 the re-loading of nsswitch.conf and all mdoules was disabled when the root filesystem changes (see bug 27077). Unfortunately php-lpfm and openldap both require the ability to continue to load NSS modules after chroot. The packages do not exec after the chroot, and so do not cause the protections to be reset. The only solution is to re-enable only NSS module loading (not nsswitch.conf reloading) and so get back the previous glibc behaviour. In the future we may introduce a way to harden applications so they do not reload NSS modules once the root filesystem changes, or that only files/dns are available pre-loaded (or builtin).

As well as the usual annual updates, mainly dates in --version output (minus csu/version.c which previously had to be handled manually but is now successfully updated by update-copyrights), there is a small change to the copyright notice in NEWS which should let NEWS get updated automatically next year. Please remember to include 2021 in the dates for any new files added in future (which means updating any existing uncommitted patches you have that add new files to use the new copyright dates in them).

* nss: Introduce <nss_module.h>Florian Weimer2020-12-044-61/+464
| | | | | | | | | | | | | | | | This provides the struct nss_module type, which combines the old struct service_library type with the known_function tree, by statically allocating space for all function pointers. struct nss_module is fairly large (536 bytes), but it will be shared across NSS databases. The old known_function handling had non-some per-function overhead (at least 32 bytes per looked-up function, but more for long function anmes), so overall, this is not too bad. Resolving all functions at load time simplifies locking, and the repeated lookups should be fast because the caches are hot at this point. Reviewed-by: Siddhesh Poyarekar <siddhesh@sourceware.org>

* nss: Make nsswitch.conf more distribution friendly.Carlos O'Donell2019-08-191-16/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current default nsswitch.conf file provided by glibc is not very distribution friendly. The file contains some minimal directives that no real distribution uses. This update aims to provide a rich set of comments which are useful for all distributions, and a broader set of service defines which should work for all distributions. Tested defaults on x86_64 and they work. The nsswitch.conf file more closely matches what we have in Fedora now, and I'll adjust Fedora to use this version with minor changes to enable Fedora-specific service providers. v2 - Add missing databases to manual. - Add link to manual from default nsswitch.conf. - Sort nsswitch.conf according to most used database first. v3 - Only mention implemented services in 'NSS Basics.' - Mention 'automount' in 'Services in the NSS configuration.' - Sort services in alphabetical order. v4 - Project name is 'Samba'. v5 - Fix typo in manual/nss.texi. v6 - Fix another typo in manual/nss.texi. Ran spell checker this time.
* nss_db: fix endent wrt NULL mappings [BZ #24695] [BZ #24696]DJ Delorie2019-07-107-2/+134
| | | | | | | | | | | | | nss_db allows for getpwent et al to be called without a set*ent, but it only works once. After the last get*ent a set*ent is required to restart, because the end*ent did not properly reset the module. Resetting it to NULL allows for a proper restart. If the database doesn't exist, however, end*ent erroniously called munmap which set errno. The test case runs "makedb" inside the testroot, so needs selinux DSOs installed.
