* nsswitch: handle missing actions properlyDJ Delorie2020-12-142-2/+6
| | | | | | | | | | | | | Some internal functions need to know if a database has a nonzero list of actions; success getting the database does not guarantee that. Add checks for such as needed. Skip the ":" in each nsswitch.conf line so as not to add a dummy action libnss_:.so See also https://bugzilla.redhat.com/show_bug.cgi?id=1906066 Reviewed-by: Siddhesh Poyarekar <siddhesh@sourceware.org>

* nss: Implement <nss_database.h>Florian Weimer2020-12-043-1/+522
| | | | | | | | | | | This code manages the mappings of the available databases in NSS (i.e. passwd, hosts, netgroup, etc) with the actions that should be taken to do a query on those databases. This is the main API between query functions scattered throughout glibc and the underlying code (actions, modules, etc). Reviewed-by: Siddhesh Poyarekar <siddhesh@sourceware.org>
* <nss_action.h>: New abstraction for combining NSS modules and NSS actionsFlorian Weimer2020-12-044-1/+423
| | | | | | | | | | nss_action manages a set of lists of actions; these are the portions of the lines in nsswitch.conf to the right of the colons, like "dns [!UNAVAIL=return] files". Each permutation of actions and conditionals is cached for reuse, which limits memory growth, and refers to the static list of modules managed by nss_modules.

* 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>
* Remove tls.h inclusion from internal errno.hAdhemerval Zanella2020-11-131-0/+1
| | | | | | | | | | | | The tls.h inclusion is not really required and limits possible definition on more arch specific headers. This is a cleanup to allow inline functions on sysdep.h, more specifically on i386 and ia64 which requires to access some tls definitions its own. No semantic changes expected, checked with a build against all affected ABIs.
* Disable warnings due to deprecated libselinux symbols used by nss and nscdArjun Shankar2020-07-231-0/+9
| | | | | | | | | | | The SELinux API deprecated several symbols in its 3.1 release, including security_context_t, matchpathcon, avc_init, and sidput, which are used in makedb and nscd. While the usage of these should eventually be replaced by newer interfaces, this commit disables GCC warnings due to the use of the above symbols.

* Remove --enable-obsolete-nsl configure flagPetr Vorel2020-07-085-28/+6
| | | | | | | | | | | | | | | | | | | this means that *always* libnsl is only built as shared library for backward compatibility and the NSS modules libnss_nis and libnss_nisplus are not built at all, libnsl's headers aren't installed. This compatibility is kept only for architectures and ABIs that have been added in or before version 2.28. Replacement implementations based on TIRPC, which additionally support IPv6, are available from <https://github.com/thkukuk/>. This change does not affect libnss_compat which does not depended on libnsl since 2.27 and thus can be used without NIS. libnsl code depends on Sun RPC, e.g. on --enable-obsolete-rpc (installed libnsl headers use installed Sun RPC headers), which will be removed in the following commit.
* nss: Remove cryptographic key support from nss_files, nss_nis, nss_nisplusFlorian Weimer2020-07-072-114/+2

* nss_compat: internal_end*ent may clobber errno, hiding ERANGE [BZ #25976]Florian Weimer2020-05-194-11/+46
| | | | | | | | | | | | During cleanup, before returning from get*_r functions, the end*ent calls must not change errno. Otherwise, an ERANGE error from the underlying implementation can be hidden, causing unexpected lookup failures. This commit introduces an internal_end*ent_noerror function which saves and restore errno, and marks the original internal_end*ent function as warn_unused_result, so that it is used only in contexts were errors from it can be handled explicitly.

* Update copyright dates not handled by scripts/update-copyrights.Joseph Myers2020-01-012-2/+2
| | | | | | | | | | | | | | | I've updated copyright dates in glibc for 2020. This is the patch for the changes not generated by scripts/update-copyrights and subsequent build / regeneration of generated files. As well as the usual annual updates, mainly dates in --version output (minus libc.texinfo which previously had to be handled manually but is now successfully updated by update-copyrights), there is a fix to sysdeps/unix/sysv/linux/powerpc/bits/termios-c_lflag.h where a typo in the copyright notice meant it failed to be updated automatically. Please remember to include 2020 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).

* Comment out initgroups from example nsswitch.conf (Bug 25146)Carlos O'Donell2019-10-291-1/+2
| | | | | | | | | | In commit 4b7c74179c8928d971d370e1137d202f891a4cf5 the nsswitch.conf file was harmonized with downstream distributions, but this change included adding "initgroups: files". We should not add initgroups by default, we can have it, but it should be commented out to allow it to inherit the settings for group. The problem is principally that downstream authconfig won't update initgroups and it will get out of sync with the setting for group.

* 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.

* nss: Turn __nss_database_lookup into a compatibility symbolFlorian Weimer2019-05-159-29/+49

Rename the function to __nss_database_lookup2 for internal use, and change __nss_database_lookup to always indicate failure to the caller. __nss_next already was a compatibility symbol. The new implementation always fails and no longer calls __nss_next2. unscd, the alternative nscd implementation, does not use __nss_database_lookup, so it is not affected by this change.

* Break some lines before not after operators.Joseph Myers2019-02-222-12/+12

This patch fixes various code to do this. It only changes code that appears to be mostly following GNU style anyway, not files and directories with substantially different formatting. It is not exhaustive even for files using GNU style (for example, changes to sysdeps files are deferred for subsequent cleanups). Some files changed are shared with gnulib, but most are specific to glibc. Changes were made manually, with places to change found by grep (so some cases, e.g. where the operator was followed by a comment at end of line, are particularly liable to have been missed by grep, but I did include cases where the operator was followed by backslash-newline). This patch generally does not attempt to address other coding style issues in the expressions changed (for example, missing spaces before '(', or lack of parentheses to ensure indentation of continuation lines properly reflects operator precedence).

* CVE-2016-10739: getaddrinfo: Fully parse IPv4 address strings [BZ #20018]Florian Weimer2019-01-211-2/+1
| | | | | | | | | | | | | | | | 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.
