* remote: Fix typo when writing a credential byteDaiki Ueno2017-03-091-1/+1
| | | | | out_fd is not always 1 when p11_kit_remote_serve_module() is used for writing a custom server.
* build: Remove systemd unit files for nowDaiki Ueno2017-03-013-39/+0
| | | | | | | | | Given that the remote proxy service shall be only used by NetworkManager and not generally useful, revert commit a4fb2bb587fb1a0146cf97f039b671d3258488f9 for now. Once the necessary command that runs the proxy module is implemented in p11-kit, maybe NetworkManager itself could install those files.
* systemd: Fix location of p11-kit-remoteDaiki Ueno2017-02-272-1/+9
| | | | | The p11-kit-remote executable is now located under $libexecdir, but we should use the p11-kit command to launch the subcommand.
* build: add missing includes for FreeBSDRoman Bogorodskiy2017-02-241-0/+1
| | | | Include signal.h for kill(2) and SIGKILL on FreeBSD.
* uri: Support vendor query attributesDaiki Ueno2017-02-213-2/+144
| | | | | | | | If an unknown attribute is present in the query part of the PKCS#11 URI, the parser treated it as unrecognized and subsequent matches failed. Instead, keep track of such attributes and provide a set of API to deal with them.
* rpc: Make it less verbose about connection failureDaiki Ueno2017-02-211-1/+1
| | | | | The connection failure here is not fatal. Use p11_debug() instead of p11_message().
* rpc: Try $XDG_CACHE_HOME before ~/.cacheMantas Mikulėnas2017-02-211-0/+11
| | | | | This is unset on most systems, but might as well follow the Base Directory spec properly.
* rpc: Add PKCS#11 module that connects to socketDaiki Ueno2017-02-178-69/+521
| | | | | | | | | | | | | | | This patch adds a PKCS#11 module that connects to the p11-kit server exposed on the filesystem. The filename of the socket is determined in the following order: - $P11_KIT_SERVER_ADDRESS, if the envvar is available - $XDG_RUNTIME_DIR/p11-kit/pkcs11, if the envvar is available - /run/$(id -u)/p11-kit/pkcs11, if /run/$(id -u) exists - /var/run/$(id -u)/p11-kit/pkcs11, if /var/run/$(id -u) exists - ~/.cache/p11-kit/pkcs11. Note that the program loading this module may have called setuid() and secure_getenv() which we use for fetching envvars could return NULL.
* remote: Add API to serve a tokenDaiki Ueno2017-02-172-0/+42

* remote, server: Recognize PKCS#11 URIDaiki Ueno2017-02-171-8/+69
|
* p11-kit: Add 'p11-kit server' commandNikos Mavrogiannopoulos2017-02-172-0/+592
| | | | | | | | This adds a new tool to the p11-kit command called 'server', which allows us to access a PKCS#11 module over a Unix domain socket. Internally, it is implemented as a wrapper around 'p11-kit remote'. Upon connection it executes 'p11-kit remote' in a forked process.
* rpc: New rpc_unix transport based on Unix socketNikos Mavrogiannopoulos2017-02-162-0/+207
|
* test: Fix modules test for WindowsDaiki Ueno2017-02-162-4/+4
| | | | | Synchronize the fixture module to the non-Unix one and enable "/modules/test_filename".
* rpc: Port exec transport to WindowsDaiki Ueno2017-02-161-30/+245
| | | | | | | On Windows, use _spawnv() to create a subprocess and two unidirectional pipe created with _pipe() to communicate with it. If we can assume WinSock, it might be simpler to use a socketpair() replacement from: https://github.com/ncm/selectable-socketpair.
* build: Adjust executable/module names for WindowsDaiki Ueno2017-02-162-3/+8
| | | | Append EXEEXT or SHLEXT to the filename if needed.
* build: Avoid undefined reference to rpc_exec_initDaiki Ueno2017-02-161-2/+3
|
* virtual: Move mutex into p11_library_init()Daiki Ueno2017-02-143-30/+5
| | | | | | | | | We used to provide p11_virtual_fixed_{,un}init() to only initialize a mutex used in virtual.c. That required all the tests calling virtual functions to call p11_virtual_fixed_{,un}init() in main(). For simplicity, move the mutex variable initialization into p11_library_init().
* filter: New virtual wrapper for access controlDaiki Ueno2017-02-084-0/+623
|
* iter: Enable iteration over slots/tokens/modulesDaiki Ueno2017-02-083-27/+295
| | | | | | | | | While PKCS#11 URI can identify slots/tokens/modules, P11KitIter is only capable of iterating over objects. This patch adds new behaviors to P11KitIter to support iterations over slots/tokens/modules, using the C coroutine trick as described in: http://www.chiark.greenend.org.uk/~sgtatham/coroutines.html
* uri: Relax pin-* parsing for compatibilityDaiki Ueno2017-02-021-5/+26
| | | | | | | | | | | | While 'pin-source' and 'pin-value' are defined as query atttribute, they were defined as path attribute in earlier drafts, and some implementations still stick to it. For backward compatibility, accept those in path attributes when parsing (but not when formatting). Reported by Andreas Metzler in: https://lists.freedesktop.org/archives/p11-glue/2017-January/000637.html
* virtual: Make virtual-fixed internal API cleanerDaiki Ueno2017-01-254-11/+16
| | | | | Add proper inclusion guard to virtual-fixed.h and move the declarations of the (un)initialization functions there.
* test: Release transport mock moduleDaiki Ueno2017-01-251-0/+1
| | | | | To prevent leaks of fixed closures, p11_kit_module_release() needs to be called on the mock module itself.
* test: Check exhaustion of fixed closuresNikos Mavrogiannopoulos2017-01-242-5/+82
|
* build: Make libffi closure optionalDaiki Ueno2017-01-249-145/+1661
| | | | | | | | libffi's closure support is not available on all platforms and may fail at run time if running under a stricter SELinux policy. Fallback to pre-compiled closures if it is not usable. https://bugs.freedesktop.org/show_bug.cgi?id=97611
* Fix compiler warnings on FreeBSDRoman Bogorodskiy2017-01-231-1/+1
| | | | | | | | | | | * common/compat.c: Fix "implicit declaration of function 'issetugid'" warning. On FreeBSD, it's required to define __BSD_VISIBLE to make issetugid(2) visible * common/test-message.c: Fix "implicit declaration of function 'asprintf'" by including <stdio.h> * p11-kit/test-iter.c: Fix "format '%lu' expects argument of type 'long unsigned int', but argument 3 has type 'int'" by changing format string to "%d"
* systemd: add per-user remoting socketLubomir Rintel2017-01-203-0/+31
| | | | | | This allows daemons outside user's session to use per-user PKCS#11 modules. Useful for letting VPN daemons or wpa_supplicant use certificates stored in user's GNOME keyring, etc.
* uri: Support query attributes to specify moduleDaiki Ueno2017-01-193-9/+237
| | | | | Accept and produce 'module-name' and 'module-path' query attributes defined in RFC 7512.
* uri: Avoid typecasting confusion on s390xDaiki Ueno2017-01-171-2/+4
| | | | | | | | | Like memcpy(), the 'void *' argument of p11_buffer_add() points to the memory area ordered in host's endianness. Add typecast of int->char to avoid the confusion. Reported by Andreas Metzler in: https://lists.freedesktop.org/archives/p11-glue/2017-January/000633.html
* uri: fix producing the query attributesLubomir Rintel2017-01-122-35/+48
| | | | Put the pin-* attributes where they belong: to the query part.
* uri: fix the query attribute parsingLubomir Rintel2017-01-122-14/+42
| | | | | | | | | | | | The pin-* attributes belong to the query part. We should not parse them until we see a '?' and they're separated with a '&'. This might be an important thing -- some of the query attributes may have security implications reaching outside scope of the token itself, to the host system itself. E.g. a pin-source may cause the consumer to access a file or module-path (unimplemented) execute code. The user may want to just chop the attribute part off if they want the consumer access the token and not take the security considerations into account.
* build: improve p11-kit-proxy symlink handlingRoman Bogorodskiy2017-01-091-1/+9
| | | | | | | | | | - Current command for creation of the p11-kit-proxy symlink uses shell brace expansion that isn't supported by all the shells (e.g. FreeBSD's /bin/sh does not support that). Replace it with the old-fashioned 'for' loop - Match extension of the source and the target, i.e. so links to so, dylib links to dylib (previously dylib linked to so) - Add an uninstall-local target to clean up the symlink

* pkg-config: Expose p11_trust_paths variableDaiki Ueno2016-11-151-0/+1
| | | | | The variable is mentioned in the manual but wasn't exposed from the pkg-config.
* build: Remove *.in files from EXTRA_DISTDaiki Ueno2016-11-151-2/+0
| | | | | The files created with AC_CONFIG_FILES are automatically added to the distribution.
* test: Remove /proxy/deinit-after-fork testDaiki Ueno2016-10-311-37/+0
| | | | | | | This test hasn't been working since the removal of the pthread_atfork() deinit code. To properly clean up, the child process needs to call C_Initialize() and C_Finalize(), and it is already tested by /proxy/initialize-child.
* modules: Reset the init count on fork()Daiki Ueno2016-10-311-0/+4
| | | | | | | | | | | | | | | Reset mod->init_count when forkid has changed. Otherwise C_Finalize does not get called.
