svn commit: r357607 - head/sys/powerpc/powerpc
Author: jhibbits

New Revision: 357607

Log:
powerpc: Fix altivec disabling in set_mcontext()
We somewhat blindly copy the srr1 from the new context to the trap frame,
but disable FPU and VSX unconditionally, relying on the trap to re-enable
them. This works because the FPU manages the VSX extended FP registers,
which is governed by the PCB_FPFREGS flag. However, with altivec, we
would blindly disable PSL_VEC, without touching PCB_VEC. Handle this case
by disabling altivec in both srr1 and pcb_flags, if the mcontext doesn't
have _MC_AV_VALID set.

This means a netmap application trying to send legitimate traffic doesn't have to calculate checksums in software. It is safe to change this at any time and it will take effect immediately. netmap(4) says that hw checksum should be disabled on the interface but cxgbe has always had a way to bypass this. It used to be via the normal csum capabilities of the interface but those sometimes caused confusion because they aren't supposed to be set with netmap so r355673 removed netmap tx checksumming. This rev brought it back with a driver-specific knob.

Log:
cxgbe(4): Add native netmap support to the main interface.
This means that extra virtual interfaces (VIs) created with
hw.cxgbe.num_vis are no longer required to use netmap. Use this
tunable to enable native netmap support on the main interface:
hw.cxgbe.native_netmap="3"
There is no change in default behavior.

[virtio] Fix r/w to PCI configuration area on big endian platforms
In legacy VirtIO drivers, the header must be PCI endianness (little) and the
device-specific region is encoded in the native endian of the guest.
This patch makes the access (read/write) to VirtIO header using the little
endian order. Other read and write access are native endianness. This also
sets the device's IO region as big endian if on big endian machine.

libssp_nonshared: use only on i386 and ppc
libssp_nonshared.a defines one symbol, __stack_chk_fail_local. This
is used only on i386 and powerpc; other archs emit calls directly to
__stack_chk_fail. Simplify linking on other archs by omitting it.

Read the breakpoint instruction to determine its length in BKPT_SKIP.
This fixes continuing from debug.kdb.enter=1 after enabling the use of
compressed instructions since the compiler can emit the two byte
c.ebreak instead of the 4 byte ebreak.

[PowerPC] [DTrace] Add ELFv2 support in libdtrace
PPC64 ELFv2 acts like a "normal" platform in that it no longer needs
function descriptors. So, ensure we are only enabling them on ELFv1.
Additionally, ELFv2 requires that the ELF header have a nonzero e_flags,
so ensure that the synthesized ELF header in dt_link.c is setting it.

(The idea of having a flag for it is just to avoid changing existing PATH behavior without an explicit admin choice, to head off arguments about security. If that's not an issue, then no need for the flag.) If there are objections to using the "daemon" class's PATH for rc/service, there could be a new "system" class added that inherits from "daemon" configured with the traditional PATH that they override with (i.e. without /usr/local paths). That would require no other changes to rc/service after modifying them to not always override PATH. And leave only the cron issue. ___ svn-src-head@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"

Author: markj Date: Wed Feb 5 19:08:21 2020 New Revision: 357585 URL: https://svnweb.freebsd.org/changeset/base/357585 Log: Define MAXCPU consistently between the kernel and KLDs. This reverts r177661. The change is no longer very useful since out-of-tree KLDs will be built to target SMP kernels anyway. Moveover it breaks the KBI in !SMP builds since cpuset_t's layout depends on the value of MAXCPU, and several kernel interfaces, notably smp_rendezvous_cpus(), take a cpuset_t as a parameter.

(The idea of having a flag for it is just to avoid changing existing PATH behavior without an explicit admin choice, to head off arguments about security.

svn commit: r357576 - head/lib/libc/rpc
Author: markj
Date: Wed Feb 5 16:10:09 2020
New Revision: 357576
URL: https://svnweb.freebsd.org/changeset/base/357576
Log:
Fix a use of an uninitialized pointer in xdr_rpcbs_rmtcalllist().
This appears to have been introduced in r173763. Also fix the confusing
indentation that probably led to the bug in the first place.

svn commit: r357574 - head/sys/kern
Author: markj
Date: Wed Feb 5 16:09:21 2020
New Revision: 357574
URL: https://svnweb.freebsd.org/changeset/base/357574
Log:
Avoid releasing object PIP in vn_sendfile() if no pages were grabbed.
sendfile(2) optionally takes a set of headers that get prepended to the
file data. If the request length is less than that of the headers,
sendfile may not allocate an sfio structure, in which case its pointer
is null and we should be careful not to dereference. This was
introduced in r356902.

Log:
wc(1): account for possibility of file == NULL
file could reasonably be NULL here if we we're using stdin. Albeit less
likely in normal usage, one could actually hit either of these warnings on
stdin.

svn commit: r357570 - head/sys/kern
Author: luporl
Date: Wed Feb 5 11:34:10 2020
New Revision: 357570
URL: https://svnweb.freebsd.org/changeset/base/357570
Log:
Add SYSCTL to get KERNBASE and relocated KERNBASE
This change adds 2 new SYSCTLs, to retrieve the original and relocated
KERNBASE
values. This provides an easy, architecture independent way to calculate the
running kernel displacement (current/load address minus original base
address).
The initial goal for this change is to add a new libkvm function that returns
the kernel displacement, both for live kernels and crashdumps. This would in
turn be used by kgdb to find out how to relocate kernel symbols (if needed).
