2010-12-15Bring CBC oracle attack countermeasure from r1.32 of cryptosoft.c toMike Belopuhov
the hardware crypto accelerator land. This fixes aes-ni, via xcrypt, glxsb(4), hifn(4), safe(4) and ubsec(4) drivers. Original commit message by angelos: Don't keep the last blocksize-bytes of ciphertext for use as the next plaintext's IV, in CBC mode. Use arc4random() to acquire fresh IVs per message. with and ok deraadt, ok markus, djm

2010-12-15oops, i forgot to check in the BRKSIZ define in uvm, but deraadt thinksTed Unangst
its better as a per arch MD define anyway. all default to MAXDSIZ as before.
2010-12-15add a BRKSIZ define and use it for the heap gap constant, decouplingTed Unangst
heap gap from max data size. nothing else changes yet. ok deraadt

the boot loader passes a variable that identifies the disk its booting off made up of a bunch of fields like adapter, controller, disk, and partition offsets, plus a table of all the disks it can see which includes this id and a checksum. the kernel goes through and checksums the disks and then maps that back to the id associated with that disk, and then compares some of the fields in those ids against the boot disks id to figure out which disk its on. the problem is we overflow one of those fields (the disk id one). since the other fields are set to 0 by the boot loader, this doesnt really matter that much. however, since those fields are now significant because of the overflow, we should compare them too. this prevents sd16 being matched as the boot disk after sd0 on my system with 25 disks attached. ok krw@ weingart@ ithe boot loader passes a variable that identifies the disk its booting off made up of a bunch of fields like adapter, controller, disk, and partition offsets, plus a table of all the disks it can see which includes this id and a checksum. the kernel goes through and checksums the disks and then maps that back to the id associated with that disk, and then compares some of the fields in those ids against the boot disks id to figure out which disk its on. the problem is we overflow one of those fields (the disk id one). since the other fields are set to 0 by the boot loader, this doesnt really matter that much. however, since those fields are now significant because of the overflow, we should compare them too. this prevents sd16 being matched as the boot disk after sd0 on my system with 25 disks attached. requested by deraadt@ ok krw@ weingart@

2010-12-04Introduce a new pci routine, pci_conf_size(), which returns the size of aMiod Vallat
given pcitag_t configuration address space. Currently, all pci controllers will return the usual 0x100 bytes of PCI configuration space, but this will eventually change on PCIe-capable controlers. ok kettenis@
2010-12-02After the most recent change, make it possible to make -j again. TheTheo de Raadt
early MD and late MI files must be split up so that vers.o can sneak between. Issue spotted by bluhm, repair discussed with miod
2010-12-02move vers.o to before the other objects, so that it is not linked last.Theo de Raadt
having it linked last is bad (on at least i386 and amd64) because the lapic is mapped over the start of the data segment -- savecore(8) then reads the version string for a fixed buffer space, and reads into the lapic area causing unintended side-effects (at least on Intel X5570 and X5680) found by pedro, discussed with kettenis and mpf and miod

2010-11-20typoMiod Vallat
2010-11-20This is a first step towards getting rid of avail_start and avail_end in theMiod Vallat
kernel, currently limited to low-hanging fruit: these variables were used by bus_dma to specify the range in which to allocate memory, back when uvm_pglistalloc() was stupid and would not walk the vm_physseg[]. Nowadays, except on some platforms for early initialization, these variables are not used, or do not need to be global variables. Therefore: - remove `extern' declarations of avail_start and avail_end (or close cousins, such as arm physical_start and physical_end) from files which no longer need to use them. - make them local variables whenever possible. - remove them when they are assigned to but no longer used.
2010-11-20Check uvm_km_alloc() return values; pmap_fork() will currently panic,Miod Vallat

2010-09-24Add stricter asserts to DIAGNOSTIC kernels to help catch mutex andMatthew Dempsky
rwlock misuse. In particular, this commit makes the following changes: 1. i386 and amd64 now count the number of active mutexes so that assertwaitok(9) can detect attempts to sleep while holding a mutex. 2. i386 and amd64 check that we actually hold mutexes when passed to mtx_leave(). 3. Calls to rw_exit*() now call rw_assert_{rd,wr}lock() as appropriate. ok krw@, oga@; "sounds good to me" deraadt@; assembly bits double checked by pirofti@
