2022-08-12add support for booting from RAID 1C softraid(4) volumes on amd64Stefan Sperling
Only boot-loader changes are needed. Both installboot(8) and the kernel already do what is required to make this work. ok kn@ Tested: biosboot on vmm: kn, stsp biosboot and efiboot on server hardware: stsp
2022-08-11Revert uLong -> z_off_t change in the kernelTheo Buehler
The kernel source assumes the original zlib ABI. There is no reason to stick to this local change. Pull in a fix matching ctfdump.c -r1.26. This is hopefully the last change necessary to undo a painful hack that was committed 19 years ago without ok. Someone owes me a lot of beer... ok millert
2022-08-09Sync inflateGetHeader() fix from userlandTheo Buehler
2022-05-08Backport an upstream fix for CRC calculation. This fixes Java applicationsTheo Buehler
on some older hardware, see https://github.com/madler/zlib/issues/613 Pointed out by tj and sthen commit ec3df00224d4b396e2ac6586ab5d25f673caa4c2 Author: Mark Adler <madler@alumni.caltech.edu> Date: Wed Mar 30 11:14:53 2022 -0700 Correct incorrect inputs provided to the CRC functions. The previous releases of zlib were not sensitive to incorrect CRC inputs with bits set above the low 32. This commit restores that behavior, so that applications with such bugs will continue to operate as before.
2022-05-08Update to zlib 1.2.12Theo Buehler
Build tests by myself for amd64 and arm64, sthen and inoguchi for i386 and gkoehler for macppc and powerpc64, thanks! Detailed changelog is part of the committed diff.

2022-03-25Sync zlib with userlandTheo Buehler
Backport zlib fix for the multi line CLEAR_HASH macro. There is an else branch where only half of the macro is executed conditionally. Acording to upstream comment this has only little impact. https://github.com/madler/zlib/commit/38e8ce32afbaa82f67d992b9f3056f281fe69259 ok bluhm (who had the same diff)

2021-12-01Fix booting from an IDE block device on the Sun Blade 100. ApparentlyMark Kettenis
writing to disk using the Open Firmware interfaces is buggy and causes corruption of the disk. While it isn't entirely clear what versions of Open Firmware are affected, but it seems to only affect IDE drives. So if we detect an IDE drive, disable writing to it. This results in a small lose of bootloader functionality (bsd.upgrade loop prevention and flagging /etc/random.seed re-use) but that is better than losing the ability to run OpenBSD at all. Based on a diff by Ted Bullock (who did all the hard work of debugging this and coming up with a viable fix). ok deraadt@

2021-07-28Fix previous: In one spot I incorrectly used Pos (unsigned short) whereTheo Buehler
I should have used Byte (unsigned char) which led to passing twice the correct size to free. Found & tested by bluhm with the sys/netinet/ipsec tests on i386.
2021-07-22Add sizes for free() in zlibTheo Buehler
Rebased version of a diff from miod who described it as follows: This tries to keep diffability against upstream, hence a questionable choice of the size type for zcfree() - but all sizes should fit in 32 bits anyway. Since all zcfree routines used in the tree cope with NULL arguments (including the various alloc.c used by the boot blocks), I have simplified TRY_FREE to compensate for the growth.

2021-07-20Remove unneeded __sync_* library functions from the kernel.Visa Hankala
These library functions were added as stopgaps because GCC 4.2.1 lacks the corresponding __sync_* builtins on mips64. However, the builtins are now provided by Clang.
2021-07-08In recent libz update, tb@ overzealously attempted codesize reduction withTheo de Raadt
option BUILDFIXED -- which is incompatible with kernel hibernate unpack since it places side-effects into BSS, rather than inside z_streamp or using the private allocator. While here DYNAMIC_CRC_TABLE could cause similar problems, so disable this also. Space savings for the media is best done with bootblock-specific libz compile options, coming in the following commit. ok tb mlarkin

This changes RETGUARD_SETUP(ffs) to RETGUARD_SETUP(ffs, %r11, %r12) and RETGUARD_CHECK(ffs) to RETGUARD_CHECK(ffs, %r11, %r12) to show that r11 and r12 are in use between setup and check, and to pick registers other than r11 and r12 in some kernel functions. ok mortimer@ deraadt@

2020-07-09Fix a warning false positive from clang 10.Todd C. Miller
blf_enc() takes a number of 64-bit blocks to encrypt, but using sizeof(uint64_t) in the calculation triggers a warning from clang 10 because the actual data type is uint32_t. Pass BCRYPT_WORDS / 2 for the number of blocks like libc bcrypt(3) does. OK kettenis@

2020-05-19If we pass a packet length larger than 2^16, we should panic() insteadPatrick Wildt
of returning -1. With a return type of u_int16_t, -1 is not different to a valid checksum. For incoming packets, the header lengths don't exceed that size anyway, but for outgoing packets it's better to see if our bootloader crafts a broken one. Discussed with gerhard@ ok deraadt@ procter@
2020-05-18Sync in_cksum.c to the same version ospfd has. This fixes problemsPatrick Wildt
with odd packet lengths, which can happen when using TFTP to load a file with an odd length. ospfd actually took dvmrpd's version in 2006 to fix the same issue, and both daemons implementations are the same. For the bootloader we keep the consts from the previous version and replace the fatal with a print and return. ok deraadt@
