with an uninitialized struct ip6_pktopts on the stack, opt.
ip6_clearpktopts(&opt, ...) could dereference dangling pointers,
leading to memory corruption or a crash. Now, udp6_output() calls
ip6_clearpktopts(&opt, ...) only if opt was initialized. Thanks to
Clement LECIGNE for reporting this bug.
Fix a potential memory leak: it is udp6_output()'s responsibility
to free its mbuf arguments on error. In the unlikely event that
sa6_embedscope() failed, udp6_output() would not free its mbuf
arguments.
I will ask for this to be pulled up to -4, -5, and -5-0.
add VM_PROT_EXECUTE protection for it.
Currently, this does not change much, as page execute permission is not
enforced for i386 (except for Xen, where BIOS calls are not used anyway).
is 4 with PAE (Xen only currently), 1 otherwise: loop should be unrolled
when PDP_SIZE is 1.
pmap_alloc_level() is used by pmap_growkernel(), the PDE is a kernel
mapping: mark it so with PG_k. While here, use pmap_pa2pte() for physical
address 'pa'.
No functional change.
nd6_storelladdr: sdl_alen == 0, dst=... if=wm1", add printfs for some
"impossible" conditions, and make the nd6_storelladdr() printf more
informative by printing the value of sdl_alen.
upper bits onto stack (we do not expect first_avail to be above 4GiB, so
assume their value is 0).
Remove macros (PROC0PDIR and PROC0STACK) that were never used.
Symlink dereference fix for Linux broke the build there; corrected.
Fix issues on ancient FreeBSD, QNX, ancient NetBSD and Minix.
Improved reliability of hash function detection.
is set to 0 and the other for the case where we set SA_RESETHAND.
The latter test is intended to expose PR port-macppc/43619 and is marked as
an expected failure on such platform.
There's no substitute for single-stepping do_sys_rename() into ffs
when trying to figure out what error should come from what layer...
well, at least apart from TNT.
- The document says that the TDH register must be set after
TCL.EN is set on 82575 and newer devices.
TODO:
- ip4csum doesn't work on 82575 and newer devices (reported by Paul Goyette),
so we have to fix it.
- Normal (valid) fragments.
- Fragment with ip_off + hlen lower than IP_MINFRAGSIZE - 1.
- Different ip_tos values in fragments.
- Fragment data length which is not multiple of 8 bytes.
- Duplicate fragments (one covering previous).
- Packet larger than IP_MAXPACKET after reassembly.
- No last non-MF fragment (causing of timeout).
This change adds the ATFFILE variable, which can take the following values:
- yes: The source directory contains a static Atffile to be installed.
- auto: The Atffile is automatically generated.
- no: Do not install any Atffile (replaces the previous NOATFFILE variable).
The ugly bit of this is that I have to add a TESTS_SUBDIRS variable that
lists the subdirectories that contain test cases (so that they can be listed
in the Atffiles, without including auxiliary directories without tests).
This is a subset of SUBDIR.
Addresses a minor part of PR bin/43394.
