mycroft 351bdbd445 Implement setre[ug]id() compatibly with 4.3BSD, SunOS, and Linux. 1996-06-23 11:04:11 +00:00
thorpej 6041e29f1f My extent map manager. Sort of like resource maps, but more flexible.
Understands allocation aligment and boundary restrictions, "specific region"
allocations, and suballocations.  Capable of statically or dynamically
allocating map overhead.

Many thanks to Matthias Drochner for running the code for me, and sending
me bug fixes, optimizations, and suggestions.  Also, many thanks to
Chris Demetriou for his extremely helpful suggestions.

XXX No manual page yet.  One is forthcoming, as soon as I can scare up
the time to write one.  This has been sitting on my plate for quite a
while, and several projects are waiting for it.  Time to move on.

mycroft 506cefab8c In the sync case of bwrite(), move the accounting earlier so that so that the
delayed write is logically converted to a sync write, mirroring the async case.
In bdwrite(), move the tape case earlier to avoid needless reassignbuf()s.

cgd d73abf41aa avoid unnecessary checks of m_get/MGET/etc.'s return values. When
they're called with M_WAIT, they are defined to never return NULL.

christos e2e0f65050 Merge pagedvn changes from OpenBSD and added mips defines. Also added
ELF_MAP_PAGE_ZERO define. The entry point computation is different than
the one OpenBSD uses.

jtc 2074cccbb8 Cast `sec' to a u_quad_t in `sec * 1000000 + usec' so the expression
is computed with quad integer arithmetic (so it won't overflow after
4294 seconds).

christos 306987eb37 - Pass the Elf exec header in the emulation dependent probe functions.

cgd 1abc77f86d if kmem_malloc() fails while trying to allocate an mbuf cluster, try
and free some space by calling m_reclaim().  Also, log the "mb_map full"
error message (at most) every 60-seconds.  The old code would log it
once over the lifetime of the system, but that's not a useful diagnostic.
(More useful is the new behaviour, which roughly indicates how often
periods of heavy load occur, without spamming the console and system
logs with messages.)
1996-06-13 17:02:23 +00:00
cgd 06c209646e handle the case where kmem_malloc() returns NULL in the 'can wait' case.
Right now, this code just panic()s (same as kmem_malloc() used to do
before, but different message), but in the future it should be modified
to try to reclaim wasted memory.

cgd f41d0a3d9b in select(), if it's a small number of file descriptors use a
automatic array rather than an array allocated with alloca().
(This was the only use of alloca() in the kernel, and it wasn't
necessary or consistent with the way other functions in this file
work.)
1996-06-13 05:08:47 +00:00
cgd 1e2b610d5a #ifdef __alpha__, call a machine-dependent function with new device
structure and 'aux', right before ca_attach is called for the
newly-attached device.  This allows the alpha port to do root device
autodetection without modifying every bus and device driver which could
be in the 'boot path.'  In the long run, it may make sense to make
this machine-independent.

cgd 57b8bdb5c3 Fix a bug where free()ing an already-free block, or even a block that looked
like it might have already been freed, would cause a crash because of a bad
pointer dereference.  Pointed out by Brian Noble <bnoble@cs.cmu.edu>.

code to panic in this case.

mycroft 49d52c9b1c Pass a proc pointer down to the usrreq and pcbbind functions for PRU_ATTACH, PRU_BIND and
PRU_CONTROL.  The usrreq interface really needs to be split up, but this will have to wait.

mycroft 261382c331 Change VOP_UPDATE() semantics:

* Consistently pass a Boolean as the 4th arg (except in LFS).

thorpej e408d7413a Fix __sysctl() to return the proper value to the caller, to match
documented behavior.  sysctl(3) is documented to return 0 on success,
-1 on failure.  The previous behavior was to return -1 on failure
and the number of bytes copied back down to user space.

cgd fbce6d4468 Make config_found_sm() (and therefore config_found()) and config_rootfound()
return a struct device * of attached device, or NULL if device attach failed,
rather than 1/0 for success/failure, so that code that bus code which needs
to know what the child device is doesn't have to open-code a hacked variant
of config_found().  Make config_attach() return struct device *, rather than
void, to facilitate that.
