2019-08-23	4753756 Browse files » fs: tftp: don't maintain tftp dentries in dcache ... Currently a negative dentry is cached whenever a non-existing file was looked up over TFTP. Short of a barebox reset, there is no way to invalidate that dentry, so barebox retries the look up. Fix this by always reporting TFTP dentries as invalid in the d_revalidate callback.

2018-11-29	4b48ae4 Browse files » net: dns: return error codes ... The resolv() function used to return the IP address. When net_udp_new() fails we return an error code though which the callers of resolv() take as an IP address. This is wrong of course and we could return 0 in this case. Instead we return an error code and pass the resolved IP as a pointer which allows us to return proper error codes. This patch also adds error messages and error returns to the various callers of resolv() which used to just continue with a zero IP and let the user figure out what went wrong.

This results in the fs layer calling fsdrv->truncate. tftp returns -ENOSYS here and open returns with an error. To fix this return 0 for the truncate callback in tftp. Also enforce the O_TRUNC flag when opening a file for writing on tftp as the files are always truncated on tftp anyway.
