* posix: Add _Fork [BZ #4737]Adhemerval Zanella2021-06-281-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | Austin Group issue 62 [1] dropped the async-signal-safe requirement for fork and provided a async-signal-safe _Fork replacement that does not run the atfork handlers. It will be included in the next POSIX standard. It allow to close a long standing issue to make fork AS-safe (BZ#4737). As indicated on the bug, besides the internal lock for the atfork handlers itself; there is no guarantee that the handlers itself will not introduce more AS-safe issues. The idea is synchronize fork with the required internal locks to allow children in multithread processes to use mostly of standard function (even though POSIX states only AS-safe function should be used). On signal handles, _Fork should be used intead and only AS-safe functions should be used. For testing, the new tst-_Fork only check basic usage. I also added a new tst-mallocfork3 which uses the same strategy to check for deadlock of tst-mallocfork2 but using threads instead of subprocesses (and it does deadlock if it replaces _Fork with fork).

* linux: Add execveat system call wrapperAlexandra Hájková2021-05-031-0/+5
| | | | | | | | | | | It operates similar to execve and it is is already used to implement fexecve without requiring /proc to be mounted. However, different than fexecve, if the syscall is not supported by the kernel an error is returned instead of trying a fallback. Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.

| | | | | | | | | | | | | | | | I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 6694 files FOO. I then removed trailing white space from benchtests/bench-pthread-locks.c and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this diagnostic from Savannah: remote: *** pre-commit check failed ... remote: *** error: lines with trailing whitespace found remote: error: hook declined to update refs/heads/master

* manual: Revise crypt.texi.Zack Weinberg2018-06-291-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a major rewrite of the description of 'crypt', 'getentropy', and 'getrandom'. A few highlights of the content changes: - Throughout the manual, public headers, and user-visible messages, I replaced the term "password" with "passphrase", the term "password database" with "user database", and the term "encrypt(ion)" with "(one-way) hashing" whenever it was applied to passphrases. I didn't bother making this change in internal code or tests. The use of the term "password" in ruserpass.c survives, because that refers to a keyword in netrc files, but it is adjusted to make this clearer. There is a note in crypt.texi explaining that they were traditionally called passwords but single words are not good enough anymore, and a note in users.texi explaining that actual passphrase hashes are found in a "shadow" database nowadays. - There is a new short introduction to the "Cryptographic Functions" section, explaining how we do not intend to be a general-purpose cryptography library, and cautioning that there _are_, or have been, legal restrictions on the use of cryptography in many countries, without getting into any kind of detail that we can't promise to keep up to date. - I added more detail about what a "one-way function" is, and why they are used to obscure passphrases for storage. I removed the paragraph saying that systems not connected to a network need no user authentication, because that's a pretty rare situation nowadays. (It still says "sometimes it is necessary" to authenticate the user, though.) - I added documentation for all of the hash functions that glibc actually supports, but not for the additional hash functions supported by libxcrypt. If we're going to keep this manual section around after the transition is more advanced, it would probably make sense to add them then. - There is much more detailed discussion of how to generate a salt, and the failure behavior for crypt is documented. (Returning an invalid hash on failure is what libxcrypt does; Solar Designer's notes say that this was done "for compatibility with old programs that assume crypt can never fail".) - As far as I can tell, the header 'crypt.h' is entirely a GNU invention, and never existed on any other Unix lineage. The function 'crypt', however, was in Issue 1 of the SVID and is now in the XSI component of POSIX. I tried to make all of the @standards annotations consistent with this, but I'm not sure I got them perfectly right. - The genpass.c example has been improved to use getentropy instead of the current time to generate the salt, and to use a SHA-256 hash instead of MD5. It uses more random bytes than is strictly necessary because I didn't want to complicate the code with proper base64 encoding. - The testpass.c example has three hardwired hashes now, to demonstrate that different one-way functions produce different hashes for the same input. It also demonstrates how DES hashing only pays attention to the first eight characters of the input. - There is new text explaining in more detail how a CSPRNG differs from a regular random number generator, and how getentropy/getrandom are not exactly a CSPRNG. I tried not to make specific falsifiable claims here. I also tried to make the blocking/cancellation/error behavior of both getentropy and getrandom clearer.
* Disallow use of DES encryption functions in new programs.Zack Weinberg2018-06-291-13/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The functions encrypt, setkey, encrypt_r, setkey_r, cbc_crypt, ecb_crypt, and des_setparity should not be used in new programs, because they use the DES block cipher, which is unacceptably weak by modern standards. Demote all of them to compatibility symbols, and remove their prototypes from installed headers. cbc_crypt, ecb_crypt, and des_setparity were already compat symbols when glibc was configured with --disable-obsolete-rpc. POSIX requires encrypt and setkey to be available when _XOPEN_CRYPT is defined, so this change also removes the definition of X_OPEN_CRYPT from <unistd.h>. The entire "DES Encryption" section is dropped from the manual, as is the mention of AUTH_DES and FIPS 140-2 in the introduction to crypt.texi. The documentation of 'memfrob' cross-referenced the DES Encryption section, which is replaced by a hyperlink to libgcrypt, and while I was in there I spruced up the actual documentation of 'memfrob' and 'strfry' a little. It's still fairly jokey, because those functions _are_ jokes, but they do also have real use cases, so people trying to use them for real should have all the information they need. DES-based authentication for Sun RPC is also insecure and should be deprecated or even removed, but maybe that can be left as TI-RPC's problem.

| | | | | | | | | | | | | | | | | | | | | | __need_getopt is misnamed; what it really means is "we want only the getopt features specified in POSIX, not the GNU extensions". Because this code is shared with gnulib, it winds up being cleanest to split getopt.h into *four* headers. getopt_core.h and getopt_ext.h will be shared with gnulib, getopt_posix.h will be just for glibc, and each project will have its own copy of getopt.h. * posix/bits/getopt_core.h, posix/bits/getopt_ext.h: New files, intended to be shared with gnulib. * posix/bits/getopt_posix.h: New file, not intended to be shared with gnulib. * posix/getopt.h: Now just includes features.h, bits/getopt_core.h, and bits/getopt_ext.h.

* Make _REENTRANT and _THREAD_SAFE aliases for _POSIX_C_SOURCE=199506L.Zack Weinberg2016-12-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | For many years, the only effect of these macros has been to make unistd.h declare getlogin_r. _POSIX_C_SOURCE >= 199506L also causes this function to be declared. However, people who don't carefully read all the headers might be confused into thinking they need to define _REENTRANT for any threaded code (as was indeed the case a long time ago). Therefore, remove __USE_REENTRANT, and make _REENTRANT and _THREAD_SAFE into synonyms for _POSIX_C_SOURCE=199506L. This will only affect programs that don't select a higher conformance level some other way. For instance, -std=c89 -D_REENTRANT will see a change in visible declarations, but -std=c99 -D_POSIX_C_SOURCE=200809L -D_REENTRANT won't, and -D_REENTRANT all by itself also won't, because _DEFAULT_SOURCE implies _POSIX_C_SOURCE > 199506. * include/features.h: Remove __USE_REENTRANT.

* Restore _POSIX2_C_VERSION definition (bug 438).Joseph Myers2015-05-221-0/+3
| | | | | | | | | | | | | | | | | | | My review of conformtest expectations for POSIX showed up that the _POSIX2_C_VERSION macro, required by POSIX and XPG standards before 2001, was missing in unistd.h, having been removed on 2003-04-03 despite those standards still being supported. This patch adds it back. As it's in the implementation namespace, there's no need for it to be conditional, and other such macros aren't conditional in this header either. Tested for x86_64 and x86 (testsuite). Note that this *does* change the installed libraries, because it affects the sysconf support (present all along) for _SC_2_C_VERSION.

| | | | | | | | | | | | | | | | | | For XPG3/XPG4 (defined __USE_XOPEN && !defined __USE_UNIX98), unistd.h declares many functions that should only be declared for __USE_MISC (none of them are in XPG3/XPG4): sethostname sethostid getdomainname setdomainname vhangup revoke profil acct getusershell endusershell setusershell daemon. The whole block with the [__USE_MISC || (__USE_XOPEN && !__USE_UNIX98)] conditional contains only functions that are not in XPG3/XPG4, so this patch simply changes the conditional. Tested for x86_64 (testsuite, and that installed stripped shared libraries are unchanged by this patch). [BZ #17665] * posix/unistd.h [__USE_MISC || (__USE_XOPEN && !__USE_UNIX98)]: Change conditional to [__USE_MISC].

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch cleans up cases of __USE_MISC that are trivially redundant after the recent substitution of __USE_MISC for __USE_BSD and __USE_SVID: either in constructs such as "defined __USE_MISC || defined __USE_MISC", or else (in the bits/mman.h case) a conditional on __USE_MISC nested inside another __USE_MISC conditional.

Thus, this patch leaves obviously redundant conditionals such as "defined __USE_MISC || defined __USE_MISC", and does not update #endif comments where they referred to BSD or SVID in words instead of the literal macro name. This is intended to facilitate patch review by separating the less mechanical changes from these purely mechanical changes into a separate patch.

* Use __glibc_block in public headers.Meador Inge2013-11-211-1/+2
| | | | | | | | | | | | As detailed in PR11157, the use of '__block' is known to interfere with keywords in some environments, such as the Clang -fblocks extension. Recently a similar issue was raised concerning the use of '__unused' and a '__glibc' prefix was proposed to create a glibc implementation namespace for these sorts of issues [1]. This patches takes that approach. [1] https://sourceware.org/ml/libc-alpha/2012-02/msg00047.html [2] http://lists.debian.org/debian-glibc/2013/11/msg00020.html
