780179e871 The rmt client in GNU cpio could have a heap overflow when a malicious
remote tape service returns deliberately crafted packets containing
more data than requested.

Fix this by checking the returned amount of data and bail out when it
is more than what we requested.

bb6ba5f6b9 Do not penalize correct or correctable VESA mode tables by calling another
VBE function.  Most problems should be corrected by the mode table sanity
check and we only need the paranoid in extremely rare cases.

09fcdf114e A ptrace(2) by one processor may trigger a promotion in the address space
of another process.  Modify pmap_promote_pde() to handle this.  (This is
not a problem on amd64 due to implementation differences.)

ad51361a2c Fix stupid typos. Some VESA BIOSes directly call BIOS interrupt handlers
within the VBE interrupt handler.  Unfortunately it was causing real mode
page faults because we were fetching instructions from bogus addresses.

920acedb80 Change the way text_addr and data_addr are computed to use the
executable status of segments instead of detecting the main text segment
by which segment contains the program entry point. This affects
obreak() and is required for correct operation of that function
on 64-bit PowerPC systems. The previous behavior was apparently
required only for the Alpha, which is no longer supported.

77acdc2565 Fix for NR-Sack code. The code was NOT working properly when
enabled. Basically most of the operations were incorrect causing
bad sacks when you enabled nr-sack. The fixes range across
4 files and unifiy most of the processing so that we only test
nr_sack flags to decide which type of sack to generate.

Optimization left for this is to combine the sack generation
code and make it capable of generating either sack thus shrinking
out a routine.

438be77d54 Now actually implement reading/refreshing/returning data from the pfTablesAddrTable
and modify the BEGEMOT-PF-MIB to add support for IPV6 address' statistics in the PF
tables via pfTablesAddrNetType and pfTablesAddrNet. While here, upgrade the
pf_tree.def file to the new format that includes enumerated values. Also make sure
to return SNMP_ERR_NOSUCHNAME for ALTQ objects, if ALTQ is disabled, so that the agent
will know to skip the pfAltq subtree when servicing GETNEXT requests from SNMP clients
(otherwise snmpwalk on begemotPf would stop at the pfAltq subtree with bsnmpd returning
SNMP_ERR_GENERR).

3b56b13e8e Be extremely careful when we determine bytes per scan line information.
First, we compare mode table data against minimum value.  If the mode table
does not make sense, we set the minimum in the mode info.  When we actually
set the mode, we try VESA BIOS function and compare it against the previous
value.  If it makes more sense, update the information.
