* Fix getprogname_linux.c for Android API < 21Simone Basso2019-05-041-0/+25
| | | | | | | This diff fixes the build of LibreSSL for Android with API < 21 where the `getprogname` system call was not part of libc. A comment in the diff itself explains in detail the issue.

* update autoconf for latest compat functionsBrent Cook2019-01-314-0/+48
|
* Handle malloc returning nullJohn Norrbin2019-01-041-2/+4
| | | Locks are required for multi-threading. If memory can't be allocated, exit the program with memory error. If we let the program continue, it will deadlock in the next part of the code anyway so better end it before.

* Copy libc compat files rather than adding into the repositorykinichiro2017-01-281-212/+0
| | | | | - remove the CP_LIBC files from repo - move tests/memmem.c to tests/compat/
* MSVSC fixesBrent Cook2017-01-161-1/+1

* add open(2) shim to handle O_BINARY and O_CLOEXECBrent Cook2017-01-161-0/+23
|
* handle EBADF, which is returned when a file is passedBrent Cook2017-01-151-3/+6
|
* Revert back to GetStdHandle, since it works fine with pipes.Brent Cook2015-12-111-6/+6
| | | | | Also include the formerly-missing NULL check, since this can fail in two ways.
* include stdint.h uint*_tBrent Cook2015-12-111-0/+1
|
* Replace STDIN_FILENO with _filenoAnthony Novatsis2015-12-111-3/+3
| | | | | Replace STDIN_FILENO with _fileno as STDIN_FILENO results in compile errors with Visual Studio 2015 (using CMake).
* only set the console mode if stdin is a console (not a pipe)Brent Cook2015-12-061-9/+21
| | | | This allows piping commands and running from a cygwin console.
* wrap gets on Windows, replacing '\r\n' with '\n'Brent Cook2015-12-051-0/+14
|
* check bounds before casting (long long) to time_tBrent Cook2015-10-211-0/+6
|
* Windows compatibility fixesBrent Cook2015-10-181-0/+12
| | | | | | | | | | | VS2013 has trouble with relative include paths for apps/openssl, so move certhash_win/apps_win.c back to apps/openssl. gmtime_r on mingw64 fails with negative time_t, override gmtime_s fails all of the time unit tests, override SHUT_RD/WR are defined in newer mingw64 headers, check before overriding
* make internal functions staticBrent Cook2015-10-151-4/+4
|
* use timegm from muslBrent Cook2015-10-151-60/+191
|
* include timegm fallbackBrent Cook2015-10-151-0/+71
|
* fix spelling of OPENSSL_cleanseBrent Cook2015-09-131-1/+1
|
* add win32-specific explicit_bzero implementationBrent Cook2015-08-031-0/+13
|
* move sleep shim to posix_win.cBrent Cook2015-07-211-0/+7
|
* add initial CMake and Visual Studio build supportBrent Cook2015-07-211-0/+24
| | | | | | | | This moves the compatibility include files from include to include/compat so we can use the awful MS C compiler <../include/> trick to emulate the GNU #include_next extension. This also removes a few old compat files we do not need anymore.
* win32 openssl CLI: preserve original echo stateBrent Cook2015-07-161-9/+9
| | | | | | | Mirror the patch to ui_openssl.c, also fix the broken conditional that made it not actually turn off echo in the first place. ok guenther@
* add check for inet_pton, nudge minimum win32 compat to 0x0501Brent Cook2015-07-021-0/+212
|
* add a missing header and fix typo in windows posix layerBrent Cook2015-06-131-1/+2
|
* refactor win32 shims into posix_win.cBrent Cook2015-06-051-0/+167
| | | | this also adds a rename shim that allows overwrites
* remove issetuigid wrappers, now that all getenv calls are gone.Brent Cook2015-04-145-213/+0
| | | | | | | | | | | From deraadt@ upstream: Remove all getenv() calls, especially those wrapped by issetugid(). getenv()'s wrapped by issetugid() are safe, but issetugid() is ... difficult to impliment on many operating systems. By accident, a grand experiment was run over the last year, where issetugid() returned 1 (the safe value) on a few operating systems. Noone noticed & complained that certain environment variables were not working.......
* Add experimental AIX support.Brent Cook2015-03-312-1/+111
| | | | | This includes a WIP failsafe issetugid for now, while research continues on the proper way to do this in a race-free fashion in AIX.
* disable system issetugid on OS X since it is not fork-safeBrent Cook2015-02-171-0/+16
| | | | | Noticed while testing similar code for AIX. ok beck@
* remove getuid/getgid fallbacks from hp-ux issetugid emulationBrent Cook2015-02-161-15/+6
| | | | | Fail closed if we cannot obtain the process flags. Noticed while looking at a similar function for AIX.
* add NetBSD shims for arc4randomBrent Cook2015-01-211-0/+3
| | | | | | The current NetBSD release, 6.1.5, fails to reseed arc4random fork. Work around it by providing arc4random/getentropy shims. Revisit when NetBSD 7 is available.
* Add support for HP-UXkinichiro2015-01-062-0/+29
| | | | | | | | | | tested on: HP-UX 11.31 ia64, gcc 4.7.1(HP AllianceOne version) gcc 4.2.3(http://hpux.connect.org.uk) HP C/aC++ HP-UX defaults to use LP32 and it treats long as 32 bit (= 4 bytes). This build forces LP64 for treating long as 64 bit.
* Add conditional compilation for windows and posix functions.Brent Cook2014-12-032-0/+421
| | | | | This adds a Windows-specific versions of several symbols from libcrypto and openssl(1).
* Use _WIN32 instead of __WIN32.宋冬生2014-11-181-1/+1
| | | | ok bcook@
* override native arc4random_buf on FreeBSDBrent Cook2014-11-031-1/+6
| | | | | | | | | | | | | | | | The FreeBSD-native arc4random_buf implementation falls back to weak sources of entropy if the sysctl fails. Remove these dangerous fallbacks by overriding locally. Unfortunately, pthread_atfork() is broken on FreeBSD (at least 9 and 10) if a program does not link to -lthr. Callbacks registered with pthread_atfork() simply fail silently. So, it is not always possible to detect a PID wraparound. I wish we could do better. This improves arc4random_buf's safety compared to the native FreeBSD implementation. Tested on FreeBSD 9 and 10. ok beck@ deraadt@
* wrap arc4random headerBrent Cook2014-10-301-0/+4
| | | | ok @doug
* Improve and simplify function and header detection logic.Brent Cook2014-10-301-3/+1
| | | | | | | | | Simplify autoconf checks by using AC_CHECK_FUNCS/HEADERS. Clarify some ambiguous dependencies around strnlen/strndup. Unconditionally enable pidwraptest for all arc4random implementations. Remove HAVE_VASPRINTF conditional, since asprintf requires vasprintf. ok @doug
* harmonize asprintf with OpenSSHBrent Cook2014-07-302-110/+13
| | | | | | | | | * use the original name for the file from OpenSSH (remove duplicate version) * add va_copy/__va_copy checks to configure * incorporate proposed fixes to openssh version: + include more system headers directly for various definitions + limit the scope of va_copy/va_end to their affected vsnprintf calls + simplify error handling, removing a dead assignment
