* Redesign the externalization APIs from the MAC Framework toRobert Watson2003-06-2318-547/+298
| | | | | | | | | | | | | | | | | | | | | | | | | | | | the MAC policy modules to improve robustness against C string bugs and vulnerabilities. Following these revisions, all string construction of labels for export to userspace (or elsewhere) is performed using the sbuf API, which prevents the consumer from having to perform laborious and intricate pointer and buffer checks. This substantially simplifies the externalization logic, both at the MAC Framework level, and in individual policies; this becomes especially useful when policies export more complex label data, such as with compartments in Biba and MLS. Bundled in here are some other minor fixes associated with externalization: including avoiding malloc while holding the process mutex in mac_lomac, and hence avoid a failure mode when printing labels during a downgrade operation due to the removal of the M_NOWAIT case. This has been running in the MAC development tree for about three weeks without problems.

This change is fully backward compatible so if you have an old /sbin/ipfw and a new kernel you are not in trouble (but you need to update /sbin/ipfw if you want to use the new features). Document the changes in the manpage. Now you can write things like ipfw add skipto 1000 iplen 0-500 which some people were asking to give preferential treatment to short packets. The 'MFC after' is just set as a reminder, because I still need to merge the Alpha/Sparc64 fixes for ipfw2 (which unfortunately change the size of certain kernel structures; not that it matters a lot since ipfw2 is entirely optional and not the default...)

* Add a f_vnode field to struct file.Poul-Henning Kamp2003-06-2229-94/+105
| | | | | | | | | | | | | | | Several of the subtypes have an associated vnode which is used for stuff like the f*() functions. By giving the vnode a speparate field, a number of checks for the specific subtype can be replaced simply with a check for f_vnode != NULL, and we can later free f_data up to subtype specific use. At this point in time, f_data still points to the vnode, so any code I might have overlooked will still work. Notes: svn path=/head/; revision=116678

| | | | | | | | | | | | | | | | | | TIOCCONS console (e.g. xconsole) via a timeout routine instead of calling into the tty code directly from printf(). This fixes a number of cases where calling printf() at the wrong time (such as with locks held) would cause a panic if xconsole is running. The TIOCCONS message buffer is 8k in size by default, but this can be changed with the kern.consmsgbuf_size sysctl. By default, messages are checked for 5 times per second. The timer runs and the buffer memory remains allocated only at times when a TIOCCONS console is active. Discussed on: freebsd-arch Notes: svn path=/head/; revision=116663

* Replace the code for reading and writing the kernel message bufferIan Dowse2003-06-226-119/+296
| | | | | | | | | | | | | | | | | | | | with a new implementation that has a mostly reentrant "addchar" routine, supports multiple message buffers in the kernel, and hides the implementation details from callers. The new code uses a kind of sequence number to represend the current read and write positions in the buffer. This approach (suggested mainly by bde) permits the read and write pointers to be maintained separately, which reduces the number of atomic operations that are required. The "mostly reentrant" above refers to the way that while it is now always safe to have any number of concurrent writers, readers could see the message buffer after a writer has advanced the pointers but before it has witten the new character.
