This function is able to generate a VTY help string based on an
array of 'struct value_string'.
|
|
The Mandriva GCC is more strict about handling format strings, the
copyright string might contain escape sequences and then any memory
could be read.

When building the doxygen documentation do not remove the other
VTY documentation files in the doc/vty folder. Create a command
that can be installed to dump all nodes and commands as XML on
the given VTY. Create a schema for the XML file and a XSL-T script
that can merge the generated file with additional information.

This actually allows for the user to override the decision and at the
same time supports compilers that might not be able to use -fPIC at
all.

no_password_check was the only initialized, non-relocated data in the
set of libraries, inverting its logic let us keep it in .bss
(non-initialized data, which is mapped to the zero page).

The old method used raw writes to the telnet FD, which is bad for
several reasons:
a) we don't know if we can actually write that many bytes to the
socket at the given time
b) the socket is still in blocking mode, so we could stall the entire
process
c) there may be weird interaction with the buffered writes of the
vty_out
Now, the print_welcome() functionality has moved to vty_hello() instead,
where we can use normal vty_out() in buffered mode.
This commit is expected to fix the garbled welcome message on arm-eglibc
targets.
It might still be a good idea to migrate the entire telnet interface to
libtelnet - but at some later time ;)

When using ^D at config nodes above the CONFIG_NODE, the
go_parent_cb function is used to go down by one node. This
is equivalent to "exit" command.

Document all facilities in the log syslog command.
|
|
There are no other commands on the set, log and mask level,
create a simple set-log-mask command and deprecate the old
way.

Before assigning a new string, free the previous one. This
assume that it was allocated with talloc which should be true
for the osmocom users.

This patch moves all GSM-specific definitions to include/osmocom/gsm.
Moreover, the headers in include/osmocore/ have been moved to
include/osmocom/core.
This has been proposed by Harald Welte and Sylvain Munaunt.
Tested with `make distcheck'.

The logging categories are registered by the applications, like
osmo-nitb, during startup. Thus, the VTY have to provide the logging
commands according to the logging categories that the application
has registered.
Before this patch, the VTY contained the logging categories
hardcoded. Thus, any change in the logging categories by the
application would not be shown by the VTY.
So far, this was not a problem because all applications used the
same logging categories. However, according to what Harald told
me, this may be a problem in the future.
This patch resolve the lack of integration between the logging
framework and the VTY by generating the VTY logging commands
from the logging categories registered.
Since this patch changes one function of the libosmocore API,
it follows another patch for the openbsc application to get in
sync with the new function layout.
I have reworked and renamed the functions:
* log_vty_category_string()
* log_vty_level_string()
to provide the new ones that generate the exact output that VTY
requires.
This patch does not release the memory allocated by
talloc_zero_size() to store the VTY strings for the commands
and the description. I found no exit function that can clean
up resources that were allocated.

This should put a useful syslog identity in place.
|
|
|
|
|
|
|
|
We can now configure logging to (multiple) files, stderr and syslog
from the vty command line in a persistent way (config file)
|
|
This will be required for mapping osmocore log levels to syslog priorities.
|
|
This is something that we should generate dynamically from
the log_info as well. This is adding bits from the cellmgr_ng.

This makes more sense in case you run BCS, SGSN and other components
on the same host. Having multiple telnet sessions with the same
prompt can otherwise be confusing.
|
|
It is easier to call these two functions from bindings than
wrapping the vty structure and figuring out the alignment of
the enum on all different ABIs.
|
|
|
|
Use SUBDIRS to build src first and the src/vty. We will need
to find the right way add the dependencies.
|
|
The method should be renamed to is child of config node
as it was comparing if vty->node > CONFIG_NODE. This is
fixing an assert in go_to_parent as we tried to find a
parent for the CONFIG_NODE.
|
|
|
|
|
|
Move the assumption that something is a child of the CONFIG_NODE
into a new function. The next step will be to use something else
for that.
|
|
This enables us to do something like <-128-127> as a numeric range.
