* net: ipv4: increase dhcp inter device timeoutMugunthan V N2015-08-131-1/+1
| | | | | | | | | | | | | | | | | | | When a system has multiple ethernet devices and during DHCP request (for using NFS), the system waits only for HZ/2 which is 500mS before switching to another interface for DHCP. There are some routers (Ex: Trendnet routers) which responds to DHCP request at about 560mS. When the system has only one ethernet interface there is no issue as the timeout is 2S and the dev xid doesn't changes and only retries. But when the system has multiple Ethernet like DRA74x with CPSW in dual EMAC mode, the DHCP response is dropped as the dev xid changes while shifting to the next device. So changing inter device timeout to HZ (which is 1S). Signed-off-by: Mugunthan V N <mugunthanvnm@ti.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* ipv4: coding style: comparison for equality with NULLIan Morris2015-04-031-2/+4
| | | | | | | | | | | | The ipv4 code uses a mixture of coding styles. In some instances check for NULL pointer is done as x == NULL and sometimes as !x. !x is preferred according to checkpatch and this patch makes the code consistent by adopting the latter form.

* net: ipv4: handle DSA enabled master network devicesFlorian Fainelli2015-01-191-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | The logic to configure a network interface for kernel IP auto-configuration is very simplistic, and does not handle the case where a device is stacked onto another such as with DSA. This causes the kernel not to open and configure the master network device in a DSA switch tree, and therefore slave network devices using this master network devices as conduit device cannot be open. This restriction comes from a check in net/dsa/slave.c, which is basically checking the master netdev flags for IFF_UP and returns -ENETDOWN if it is not the case. Automatically bringing-up DSA master network devices allows DSA slave network devices to be used as valid interfaces for e.g: NFS root booting by allowing kernel IP autoconfiguration to succeed on these interfaces. On the reverse path, make sure we do not attempt to close a DSA-enabled device as this would implicitely prevent the slave DSA network device from operating.

* ipconfig: add informative timeout messages while waiting for carrierPaul Gortmaker2013-04-021-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 3fb72f1e6e6165c5f495e8dc11c5bbd14c73385c ("ipconfig wait for carrier") added a "wait for carrier on at least one interface" policy, with a worst case maximum wait of two minutes. However, if you encounter this, you won't get any feedback from the console as to the nature of what is going on. You just see the booting process hang for two minutes and then continue. Here we add a message so the user knows what is going on, and hence can take action to rectify the situation (e.g. fix network cable or whatever.) After the 1st 10s pause, output now begins that looks like this: Waiting up to 110 more seconds for network. Waiting up to 100 more seconds for network. Waiting up to 90 more seconds for network. Waiting up to 80 more seconds for network. ... Since most systems will have no problem getting link/carrier in the 1st 10s, the only people who will see these messages are people with genuine issues that need to be resolved.

* ipconfig: add nameserver IPs to kernel-parameter ip=Christoph Fritz2012-09-211-3/+36
| | | | | | | | | | | | | | On small systems (e.g. embedded ones) IP addresses are often configured by bootloaders and get assigned to kernel via parameter "ip=". If set to "ip=dhcp", even nameserver entries from DHCP daemons are handled. These entries exported in /proc/net/pnp are commonly linked by /etc/resolv.conf. To configure nameservers for networks without DHCP, this patch adds option <dns0-ip> and <dns1-ip> to kernel-parameter 'ip='.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ipv4: Remove all uses of LL_ALLOCATED_SPACE The macro LL_ALLOCATED_SPACE was ill-conceived. It applies the alignment to the sum of needed_headroom and needed_tailroom. As the amount that is then reserved for head room is needed_headroom with alignment, this means that the tail room left may be too small.

Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

| | | | | | | | | | | | | | | | | | Some network devices, particularly USB ones, take several seconds to fully init and appear in the device list. If the user turned ipconfig on, they are using it for NFS root or some other early booting purpose. So it makes no sense to just flat out fail immediately if the device isn't found. It also doesn't make sense to just jack up the initial wait to something crazy like 10 seconds. Instead, poll immediately, and then periodically once a second, waiting for a usable device to appear.

* ipv4: teach ipconfig about the MTU option in DHCPChris Friesen2009-05-201-4/+37
| | | | | | | | | | | | | | | | The DHCP spec allows the server to specify the MTU. This can be useful for netbooting with UDP-based NFS-root on a network using jumbo frames. This patch allows the kernel IP autoconfiguration to handle this option correctly. It would be possible to use initramfs and add a script to set the MTU, but that seems like a complicated solution if no initramfs is otherwise necessary, and would bloat the kernel image more than this code would. This patch was originally submitted to LKML in 2003 by Hans-Peter Jansen. Signed-off-by: Chris Friesen <cfriesen@nortel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* ipconfig: handle case of delayed DHCP serverChris Friesen2009-05-181-0/+12
| | | | | | | | | | | | | | | | If a DHCP server is delayed, it's possible for the client to receive the DHCPOFFER after it has already sent out a new DHCPDISCOVER message from a second interface. The client then sends out a DHCPREQUEST from the second interface, but the server doesn't recognize the device and rejects the request. This patch simply tracks the current device being configured and throws away the OFFER if it is not intended for the current device. A more sophisticated approach would be to put the OFFER information into the struct ic_device rather than storing it globally.
