Comment fixes.

not attempted.
2019-12-05Shrink scsi_mode_do_sense() parameter list by eliminating the threeKenneth R Westerback
pointers returning possible block descriptor values for block size, block count and density. Most calls were passing "NULL, NULL, NULL" since they did not care. Call scsi_parse_blkdesc() directly in those few cases where one or more of the values is of interest. No intentional functional change.
2019-12-05No need for 'byte2' parameter to scsi_mode_sense[_big]() since weKenneth R Westerback
always pass 0. i.e. never disable block descriptors, never accept long LBA values.
2019-12-05Move prototypes for scsi_mode_sense(), scsi_mode_sense_big(),Kenneth R Westerback
scsi_mode_sense_page() and scsi_mode_sense_big_page() into scsi_base.c. They are just internal helper functions for scsi_do_mode_sense().

2019-12-04Fix a bad offset calculation in uvm_share.Mike Larkin
Syzkaller found a bug in uvm_share when using a vmd(8) mmap region with an offset that ended up making an overlap with a previous vmm(4) uvm_map range. This diff reworks the range and offset calculation in uvm_share. Only vmm(4) uses this, so there should be no visible effects outside vmm(4) environments. Syzkaller also went sorta crazy on this one, finding multiple reproducers for the same bug with just slightly different parameters, thus the multiple "Reported-by" lines below. ok stefan@, anton@ Reported-by: syzbot+2c625ab1b8e964da644a@syzkaller.appspotmail.com Reported-by: syzbot+1300829862412751462d@syzkaller.appspotmail.com Reported-by: syzbot+27cfad3394f34528cbec@syzkaller.appspotmail.com Reported-by: syzbot+3e700c5698177f91cce1@syzkaller.appspotmail.com
2019-12-04Fix uvm_unmap_remove panic when tearing down VMs.Mike Larkin
Type confusion when tearing down a vmm(4) VM's vm_map led UVM to interpret the vm_map as a struct uvmspace, and occasionally fail. stefan@ pointed out the root cause a while back but I never had time to look at this until now. Syzkaller also found a reproducer for this, so the "Reported by" line below is a clue to let it know to close that bug. idea by, and ok stefan@ also ok anton@ Reported-by: syzbot+dbd6e2a7583e958e69f8@syzkaller.appspotmail.com

2019-12-02tc_windup: separate timecounter.tc_freq_adj from timehands.th_adjustmentcheloha
We currently mix timecounter.tc_freq_adj and timehands.th_adjtimedelta in ntp_update_second() to produce timehands.th_adjustment, our net skew. But if you set a low enough adjfreq(2) adjustment you can freeze time. This prevents ntp_update_second() from running again. So even if you then set a sane adjfreq(2) you cannot unfreeze time without rebooting. If we just reread timecounter.tc_freq_adj every time we recompute timehands.th_scale we avoid this trap. visa@ notes that this is more costly than what we currently do but that the cost itself is negligible. Intuitively, timecounter.tc_freq_adj is a constant skew and should be handled separately from timehands.th_adjtimedelta, an adjustment that we chip away at very slowly. tedu@ notes that this problem is sort-of an argument for imposing range limits on adjfreq(2) inputs. He's right, but I think we should still separate the counter adjustment from the adjtime(2) adjustment, with or without range limits. ok visa@

2019-12-01Change Elf64 types and structs to match the System V ABI specification.Jonathan Gray
Change Elf64_Half from a uint32_t type to a uint16_t type. The size of structs do not change as the previous uses of Elf64_Half become Elf64_Word (uint32_t). Remove Elf64_Quarter as 16 bit values now use Elf64_Half. Replace Elf_Byte use with unsigned char. Change some uses of Elf64_Xword to Elf64_Addr (both uint64_t). Corrects behaviour with libelf where the file size of a symtab section came back as 26 not 24 as libelf determines this by the size of a the involved types not the size of the struct in exec_elf.h. As a result libelf's elf_getdata() returned ELF_E_SECTION due to the size of the section not being a multiple of the file size of the section type. This occurred with the new runtime linker for radeon shaders in Mesa 19.2. Sync description of Elf32 and Elf64 types in elf(5) with FreeBSD and adjust types in structs mentioned. ok guenther@ deraadt@
