2011-03-12Be more paranoid when attempting to parse an IA record, and make sure weMiod Vallat
won't try to read past the end of the record, no matter what kind of garbage it may contain. No functional change on IP35 systems with valid IA records.

2011-03-12In the original sparc V7 book (and in the v8 book), the divrem leaf code usedTheo de Raadt
local registers for a few temporaries. This was changed to use two global registers. Maybe to permit use in-kernel without conflicting with the register V7 register window handlers. (Was this done by Chris Torek? Is this related to Gordon Irlam's work? Or was it in NetBSD? Hard to tell because NetBSD removed their original cvs tree.) In V8 the ABI was tightened; more global registers became offlimits in different ways. We started supporting sun4m, and did not consider this. As a result, the global registers chosen are the wrong choice. In particular, %g7 is a poor choice for upcoming TLS work. It looks like it is safer to use %g5 and %g6 since these functions are "system software". All re-entrant parts of the system save it. On sparc64 these functions are in libc per ABI requirement, but are unused. On sparc, they occur in bootblocks (no reentrancy), kernel (reentrancy saves globals; kernel is not ABI compliant), userland libc (signal handlers save globals), and ld.so (symbol binding is not re-entrant on its own). Discussed rather extensively with guenther, kettenis, miod and drahn.
2011-03-12There existed a race when a process was trying to read from a splicedAlexander Bluhm
socket. soreceive() releases splsoftnet for uiomove(). In that moment, somove() could pull the mbuf from the receive buffer. After that, soreceive removed the mbuf again. The corrupted length accounting resulted in a panic. The fix is to block read calls in soreceive() until splicing has been finished. just commit deraadt@
2011-03-12Replace the old, broken KERN_PROC ABI and its matching functionsPhilip Guenthe
in libkvm with the stable-ABI versions that are currently named KERN_PROC2, kvm_get{proc,argv,envv}2(). The latter names and symbols will continue to be supported for a few releases. Committing now that they ports people have had a couple releases to update pkgs that usd the old functions

2011-03-12Provide distinct segments for the %fs and %gs selectors to use byPhilip Guenthe
default, with per-rthread base offsets and with sysarch() functions, I386_{GET,SET}_{FS,GS}BASE, for fetching and setting those base offsets. This is necessary for both rthread and Linux compat support. suggestions from kettenis@, prodding from pirofti@ and deraadt@

2011-03-08Fix a subtle carp reconfiguration problem.Marco Pfatschbacher
Updating the HMAC from the carp_ioctl call does not see the newly set IP address in the if_addrlist. The only chance for carp to see the new address is via the address-hook callback. This change moves the detection of address changes entirely into carp_addr_updated. Furthermore, only call carp_hmac_prepare for the SIOCSVH case. This second bug was the reason why the first one went unnoticed for such a long time. Problem found and debugging help by camield@. OK camield@

2011-03-08Fix extended partition searching so we don't get lost. The offsetKenneth R Westerback
of the next EBR is relative to the start of the extended partition described in the first MBR, not relative to the EBR specifying the offset in its extended partition entry. Clean up installboot -v output. Use daddr64_t for all sector numbers. Not a complete fix, but better than what we had. More tweaks to come. Inspired by a diff and cluebat from uscav on tech@ a few weeks ago. Feedback from matthew@, weingart@. ok deraadt@

2011-03-05since the bus_space_barrier function does the same membar operation forTheo de Raadt

2011-03-01back out r1.162, the one that bumps openings up on sas and fcDavid Gwynne
devices. my theory is that some devices report queue full conditions in ways the firmware doesnt understand, or some firmwares default to NOT doing the queue full handling internally. either way it reports queue full conditions as faulted io which gets passed up to the block layer as errors. this makes us conservative again and safe. this fixes panics from ajacout ok sthen@ deraadt@
