* Merge from contrib/openbsm to bring the kernel audit bits up to date with ↵brueffer2015-12-208-9/+1
| | | | | | | OpenBSM 1.2 alpha 4: - remove $P4$ - fix a comment
* IFp4 @1192291:pjd2014-04-071-1/+8
| | | | | | | | | | - Don't include sys/caprights.h, leverage the fact that cap_rights_t is also defined in sys/types.h. - Include sys/types.h directly. - For systems that do not have cap_rights_t, define it, so we can use it in au_to_rights() prototype. Discussed with: rwatson
* Change the cap_rights_t type from uint64_t to a structure that we can extendpjd2013-09-052-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | in the future in a backward compatible (API and ABI) way. The cap_rights_t represents capability rights. We used to use one bit to represent one right, but we are running out of spare bits. Currently the new structure provides place for 114 rights (so 50 more than the previous cap_rights_t), but it is possible to grow the structure to hold at least 285 rights, although we can make it even larger if 285 rights won't be enough. The structure definition looks like this: struct cap_rights { uint64_t cr_rights[CAP_RIGHTS_VERSION + 2]; }; The initial CAP_RIGHTS_VERSION is 0. The top two bits in the first element of the cr_rights[] array contain total number of elements in the array - 2. This means if those two bits are equal to 0, we have 2 array elements. The top two bits in all remaining array elements should be 0. The next five bits in all array elements contain array index. Only one bit is used and bit position in this five-bits range defines array index. This means there can be at most five array elements in the future. To define new right the CAPRIGHT() macro must be used. The macro takes two arguments - an array index and a bit to set, eg. #define CAP_PDKILL CAPRIGHT(1, 0x0000000000000800ULL) We still support aliases that combine few rights, but the rights have to belong to the same array element, eg: #define CAP_LOOKUP CAPRIGHT(0, 0x0000000000000400ULL) #define CAP_FCHMOD CAPRIGHT(0, 0x0000000000002000ULL) #define CAP_FCHMODAT (CAP_FCHMOD | CAP_LOOKUP) There is new API to manage the new cap_rights_t structure: cap_rights_t *cap_rights_init(cap_rights_t *rights, ...); void cap_rights_set(cap_rights_t *rights, ...); void cap_rights_clear(cap_rights_t *rights, ...); bool cap_rights_is_set(const cap_rights_t *rights, ...); bool cap_rights_is_valid(const cap_rights_t *rights); void cap_rights_merge(cap_rights_t *dst, const cap_rights_t *src); void cap_rights_remove(cap_rights_t *dst, const cap_rights_t *src); bool cap_rights_contains(const cap_rights_t *big, const cap_rights_t *little); Capability rights to the cap_rights_init(), cap_rights_set(), cap_rights_clear() and cap_rights_is_set() functions are provided by separating them with commas, eg: cap_rights_t rights; cap_rights_init(&rights, CAP_READ, CAP_WRITE, CAP_FSTAT); There is no need to terminate the list of rights, as those functions are actually macros that take care of the termination, eg: #define cap_rights_set(rights, ...) \ __cap_rights_set((rights), __VA_ARGS__, 0ULL) void __cap_rights_set(cap_rights_t *rights, ...); Thanks to using one bit as an array index we can assert in those functions that there are no two rights belonging to different array elements provided together. For example this is illegal and will be detected, because CAP_LOOKUP belongs to element 0 and CAP_PDKILL to element 1: cap_rights_init(&rights, CAP_LOOKUP | CAP_PDKILL); Providing several rights that belongs to the same array's element this way is correct, but is not advised. It should only be used for aliases definition. This commit also breaks compatibility with some existing Capsicum system calls, but I see no other way to do that. This should be fine as Capsicum is still experimental and this change is not going to 9.x. Sponsored by: The FreeBSD Foundation

Now every descriptor has set of its own capability rights. - The cap_new(2) system call is left, but it is no longer documented and should not be used in new code. - The new syscall cap_rights_limit(2) should be used instead of cap_new(2), which limits capability rights of the given descriptor without creating a new one. - The cap_getrights(2) syscall is renamed to cap_rights_get(2). - If CAP_IOCTL capability right is present we can further reduce allowed ioctls list with the new cap_ioctls_limit(2) syscall. List of allowed ioctls can be retrived with cap_ioctls_get(2) syscall. - If CAP_FCNTL capability right is present we can further reduce fcntls that can be used with the new cap_fcntls_limit(2) syscall and retrive them with cap_fcntls_get(2). - To support ioctl and fcntl white-listing the filedesc structure was heavly modified. - The audit subsystem, kdump and procstat tools were updated to recognize new syscalls. - Capability rights were revised and eventhough I tried hard to provide backward API and ABI compatibility there are some incompatible changes that are described in detail below: CAP_CREATE old behaviour: - Allow for openat(2)+O_CREAT. - Allow for linkat(2). - Allow for symlinkat(2). CAP_CREATE new behaviour: - Allow for openat(2)+O_CREAT. Added CAP_LINKAT: - Allow for linkat(2). ABI: Reuses CAP_RMDIR bit. - Allow to be target for renameat(2). Added CAP_SYMLINKAT: - Allow for symlinkat(2). Removed CAP_DELETE. Old behaviour: - Allow for unlinkat(2) when removing non-directory object. - Allow to be source for renameat(2). Removed CAP_RMDIR. Old behaviour: - Allow for unlinkat(2) when removing directory. Added CAP_RENAMEAT: - Required for source directory for the renameat(2) syscall. Added CAP_UNLINKAT (effectively it replaces CAP_DELETE and CAP_RMDIR): - Allow for unlinkat(2) on any object. - Required if target of renameat(2) exists and will be removed by this call. Removed CAP_MAPEXEC. CAP_MMAP old behaviour: - Allow for mmap(2) with any combination of PROT_NONE, PROT_READ and PROT_WRITE. CAP_MMAP new behaviour: - Allow for mmap(2)+PROT_NONE. Added CAP_MMAP_R: - Allow for mmap(PROT_READ). Added CAP_MMAP_W: - Allow for mmap(PROT_WRITE). Added CAP_MMAP_X: - Allow for mmap(PROT_EXEC).

OpenBSM 1.1 alpha 3 - Add two new functions, au_bsm_to_errno() and au_errno_to_bsm(), to map between BSM error numbers (largely the Solaris definitions) and local errno(2) values for 32-bit and 64-bit return tokens. This is required as operating systems don't agree on some of the values of more recent error numbers. - Fix a bug how au_to_exec_args(3) and au_to_exec_env(3) calculates the total size for the token. This bug resulted in "unknown" tokens being printed after the exec args/env tokens. - Support for AUT_SOCKET_EX extended socket tokens, which describe a socket using a pair of IPv4/IPv6 and port tuples. - OpenBSM BSM file header version bumped for 1.1 release. - Deprecated Darwin constants, such as TRAILER_PAD_MAGIC, removed.

Obtained from: TrustedBSD Project -- OpenBSM 1.1 alpha 2 - Include files in OpenBSM are now broken out into two parts: library builds required solely for user space, and system includes, which may also be required for use in the kernels of systems integrating OpenBSM. Submitted by Stacey Son. - Configure option --with-native-includes allows forcing the use of native include for system includes, rather than the versions bundled with OpenBSM. This is intended specifically for platforms that ship OpenBSM, have adapted versions of the system includes in a kernel source tree, and will use the OpenBSM build infrastructure with an unmodified OpenBSM distribution, allowing the customized system includes to be used with the OpenBSM build. Submitted by Stacey Son. - Various strcpy()'s/strcat()'s have been changed to strlcpy()'s/strlcat()'s or asprintf(). Added compat/strlcpy.h for Linux. - Remove compatibility defines for old Darwin token constant names; now only BSM token names are provided and used. - Add support for extended header tokens, which contain space for information on the host generating the record. - Add support for setting extended host information in the kernel, which is used for setting host information in extended header tokens. The audit_control file now supports a "host" parameter which can be used by auditd to set the information; if not present, the kernel parameters won't be set and auditd uses unextended headers for records that it generates. OpenBSM 1.1 alpha 1 - Add option to auditreduce(1) which allows users to invert sense of matching, such that BSM records that do not match, are selected. - Fix bug in audit_write() where we commit an incomplete record in the event there is an error writing the subject token. This was submitted by Diego Giagio. - Build support for Mac OS X 10.5.1 submitted by Eric Hall. - Fix a bug which resulted in host XML attributes not being arguments so that const strings can be passed as arguments to tokens.

* Add support for extended header BSM tokens. Currently we use thecsjp2008-11-112-0/+5
| | | | | | | | | | | | | | | | | | | | | | regular header tokens. The extended header tokens contain an IP or IPv6 address which makes it possible to identify which host an audit record came from when audit records are centralized. If the host information has not been specified, the system will default to the old style headers. Otherwise, audit records that are created as a result of system calls will contain host information. This implemented has been designed to be consistent with the Solaris implementation. Host information is set/retrieved using the A_GETKAUDIT and A_SETKAUDIT auditon(2) commands. These commands require that a pointer to a auditinfo_addr_t object is passed. Currently only IP and IPv6 address families are supported. The users pace bits associated with this change will follow in an openbsm import. Reviewed by: rwatson, (sson, wsalamon (older version)) MFC after: 1 month
* When MPSAFE ttys were merged, a new BSM audit event identifier wasrwatson2008-08-241-1/+1
| | | | | | | | | | | | | | allocated for posix_openpt(2). Unfortunately, that identifier conflicts with other events already allocated to other systems in OpenBSM. Assign a new globally unique identifier and conform better to the AUE_ event naming scheme. This is a stopgap until a new OpenBSM import is done with the correct identifier, so we'll maintain this as a local diff in svn until then. Discussed with: ed Obtained from: TrustedBSD Project
* Integrate the new MPSAFE TTY layer to the FreeBSD operating system.ed2008-08-201-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.
