2019-08-03In the bootblocks, after discovering and opening /bsd.upgrade, fchmod -xTheo de Raadt
so the file cannot be re-executed upon the next boot. This provides a stronger one-shot-upgrade model than the upgrade script's rm /bsd.upgrade. Now various forms of upgrade failure will reboot into /bsd, which is probably more recoverable. Performing fchmod -x depends on (1) use of MI boot.c (not alpha/macppc/sparc64/sgi/octeon) and (2) "can write blocks" functionality in the IO layer. Most architectures have this support now. Two diagnostics "fchmod a-x %s: failed" and "/bsd.upgrade is not u+x" will remain in the tree while refinements happen for some of the laggard architectures. based upon a discussion florian tested in snapshots for more than a week without any complaints
2019-06-01Fix warnings when building zlib with ZLIB_CONST definedJeremie Courreges-Anglas
Probably not very useful (given the lack of feedback) but feels more correct. Kernel part tested with option ZLIB_CONST.
2019-05-12Add ZLIB_CONSTJeremie Courreges-Anglas
Introduced in zlib-1.2.5.2, used by a few ports. ok deraadt@

fails and locks early in boot.
2019-04-20libsa's memcpy() is actually memmove(). make a proper memmove(), and giveTheo de Raadt
memcpy() correct behaviour. This also brings the bcopy() macro into line.

details from the ELF header instead of faking it. Proposal from mlarkin, tested on most architectures already

2018-08-10Retry on incorrect passphrase for softraid crypto boot.Joel Sing
Historically, the softraid crypto support in the boot loaders has only given one attempt to provide the correct passphrase. There were a few reasons for this, including the fact that pkcs5_pbkdf2() allows an empty passphrase and that returning EPERM allowed for another attempt. With the event of KARL and the need for bsd.booted with hibernate resumption, this becomes much more of an issue - if you get the passphrase wrong you fail to resume. There are also other situations like using /etc/boot.conf to switch serial console, but an incorrect passphrase results in the config not being read. Also, bcrypt_pbkdf() does not permit empty passphrases. This reworks the softraid crypto support in the boot loaders so that it loops requesting a valid passphrase until one is provided, or an empty passphrase is entered (at which point it will abort). ok mortimer@ tb@

ENTRY is a trapsled. Fix a few functions which fall-through into an ENTRY macro. amd64 binaries now are free of double+-nop sequences (except for one assember nit in aes-586.pl). Previous changes by guenther got us here. ok mortimer kettenis

2018-03-31Stop converting UDP and IP header values from network endianness to hostPatrick Wildt
endianness for convenience reasons. Especially in code pathes like TFTP where the source port is read from the received UDP packet and used as destination port in a new UDP packet this can be very harmful. Luckily this issue has had no effect on our architectures since they never use any of the code paths that could be harmful. ok visa@
