Petr Machata says:
====================
When a list of filters at a given block is requested, tc first validates
that the block exists before doing the filter query. Currently the
validation routine checks ingress and egress blocks. But now that blocks
can be bound to qevents as well, qevent blocks should be looked for as
well:
# ip link add up type dummy
# tc qdisc add dev dummy1 root handle 1: \
red min 30000 max 60000 avpkt 1000 qevent early_drop block 100
# tc filter add block 100 pref 1234 handle 102 matchall action drop
# tc filter show block 100
Cannot find block "100"
This patchset fixes this issue:
# tc filter show block 100
filter protocol all pref 1234 matchall chain 0
filter protocol all pref 1234 matchall chain 0 handle 0x66
not_in_hw
action order 1: gact action drop
random type none pass val 0
index 2 ref 1 bind 1
In patch #1, the helpers and necessary infrastructure is introduced,
including a new qdisc_util callback that implements sniffing out bound
blocks in a given qdisc.
In patch #2, RED implements the new callback.
v3:
- Patch #1:
- Do not pass &ctx->found directly to has_block. Do it through a
helper variable, so that the callee does not overwrite the result
already stored in ctx->found.
v2:
- Patch #1:
- In tc_qdisc_block_exists_cb(), do not initialize 'q'.
- Propagate upwards errors from q->has_block.

How to compile this.
--------------------
1. libdbm
arpd needs to have the berkeleydb development libraries. For Debian
users this is the package with a name like libdbX.X-dev.
DBM_INCLUDE points to the directory with db_185.h which
is the include file used by arpd to get to the old format Berkeley
database routines. Often this is in the db-devel package.
2. make
The makefile will automatically build a config.mk file which
contains definitions of libraries that may or may not be available
on the system such as: ATM, ELF, MNL, and SELINUX.
3. To make documentation, cd to doc/ directory , then
look at start of Makefile and set correct values for
PAGESIZE=a4 , ie: a4 , letter ... (string)
PAGESPERPAGE=2 , ie: 1 , 2 ... (numeric)
and make there. It assumes, that latex, dvips and psnup
are in your path.
4. This package includes matching sanitized kernel headers because
the build environment may not have up to date versions. See Makefile
if you have special requirements and need to point at different
kernel include files.
